PDF, JPG, TIF / PC or MAC
PDF is highly recommended.

This depends on what the final output size will be, and its viewing distance.
Please reference our Scale & Resolution Example Chart and Letter Visibility Chart below:

It is not always necessary to scale your artwork. Scaling artwork can help to keep the file size manageable. Here are a few things to keep in mind if you are scaling your artwork.

Vector Art
Grand4mat is able to print outdoor banners as large as 150ft x 16ft, however most software is not able to produce an art board larger than 228". Adobe Acrobat and other PDF readers / converters are only able to view a maximum file size of 200", resulting in a loss of artwork. For this reason, it is recommended to submit files at a smaller scale than the ordered size.

Raster Art
Raster files are calculated by pixels rather than inches. The pixels are converted to inches based on the resolution of a file. The equation for the conversion is (pixels divided by dpi = inches). Raster files have a limitation of 30,000 pixels. A file that is 30,000 pixels set at 150 dpi will be 16' (200"). If your artwork is more than 30,000 pixels, we recommend dropping your dpi or scaling down your artwork.

Resolution & Scale Charts
Grand4Mat is fully automated and expands/constricts file sizes to the ordered size. Resolution varies based on the substrate and ink used to print the final product. If your artwork needs to be scaled, we recommend using the following information as a basic guide:

Outdoor Banners:
Full scale at approximately 100dpi
Half scale at approximately 200dpi
Quarter scale at approximately 300dpi

Note: Banners larger than 15 feet will print below 100dpi

Flags:
Full scale at approximately 150dpi

Canvas:
Full scale at approximately 250dpi

Coroplast and Adhesive Vinyl
Full scale at approximately 200dpi

Foamcore:
Full scale at approximately 250dpi

PVC:
Full scale at approximately 250dpi

Indoor Banners, Car Magnets, Floor Graphics and Large Posters:
Full scale at approximately 300dpi

Table Runners:
Full scale at approximately 200dpi

Adhesive Vinyl:
Full scale at 100 dpi. vector artwork is preferred

No, please ensure all fonts are outlined prior to file upload. If using Photoshop, please provide the flattened file only.

Absolutely not. Grand4mat's upload and design tool gives us exactly what we need to know when trimming your order. Please do not include crop marks, color bars, registration marks or any other indicators that you do not want printed on the final piece.

Yes. Borders are an issue because all substrates will vary from batch to batch making exact cuts very difficult. We recommend that you do not design your file with a border. If you do Grand4mat will not reprint an order with borders of varying widths. If you absolutely must have a border make it at least 2 inches in thickness, however Grand4mat still does not recommend borders.

Primarily used to intentionally overlap inks for a number of reasons, overprint can cause unexpected results. We suggest that you turn all overprint objects off before submitting your files.

After Printing

In this case the logo was set to overprint. The colors from logo are mixing with the colors from the background. Unexpected results may occur if you have accidentally set certain objects to overprint. Always check logos and other artwork before submitting.

Rich black is an ink mixture of solid black, 100% K, with additional CMY ink values. This results in a darker tone than black ink alone. If you print black alone as 100% K, the resulting black may not be as dark as you might like.

100% K on screen

100% K after print

We recommend using
C 60 M 40 Y 40 K 100
This will give you a deep, dark, rich black.

*Products that are printed with dye-sublimation (9oz Premium Polyester Banner, Flags, Table Covers, Fabric Tube Displays, etc.)
call for the following color values:
C 100 M 100 Y 100 K 100

Grayscale images that are converted to CMYK will have a color shift in the final print. That shift may be green or yellow.

Grayscale On Screen

Grayscale After Print

Always check the CMYK values of your grayscale in the final CMYK document. If there are other values other then K in your grayscale image, there is a chance that the color will vary.

To eliminate all values other then K, use your Channel Mixer (adjustment layer) in Photoshop, then click "Monochrome" and adjust accordingly.

When using a blue in your design, always make sure to leave at least a 30% difference in your Cyan and Magenta values.

100% C 100% M 0% Y 0% K

On Screen

After Printing

Blue is close to purple in the CMYK spectrum. Remember, use a low amount of magenta whenever using high amounts of cyan to avoid purple.

Example: C-100 M-70 Y-0 k-0

If you send us an RGB file, there is a chance that a color shift may occur and you may not be satisfied with your job.

These colors are in RGB

These are the same colors but in CMYK

You should always start and finish your designs in CMYK color mode. Never use PMS or Pantone Colors.

Often times, your artwork itself is set-up correctly - however, when you save as PDF - your PDF file will only output the size you have in your document set-up. To ensure your bleed is always acknowledged, you must include the bleed on your artboard (Document Set-up) in addition to the actual size of your finished size desired. i.e. If you order a 24" x 18" Coroplast, your artwork with bleed and document set-up both should actually be 25" x 19".

No. Even the smallest transparency issue will cause problems with a printed file. It is always best to flatten any file you send to Grand4mat. Outline fonts and ensure that your file is in CMYK mode for best results. Grand4mat considers flattening transparency part of basic file setup and will not check for this issue. If you are uncertain how to flatten transparencies in your file or if you would like us to explain how to check for transparency problems please contact Grand4mat prior to submitting an order.

At this time Grand4Mat can only accept 1 piece of artwork for any single job of any quantity.

Different versions of Illustrator– have different presets in the "Save PDF" dialog. The PDF presets in Illustrator CS will not save the PDF to the correct document size if any artwork extends past the edge of the document size. It will include all objects, including those that are not visible, producing a PDF with excess white space. This will produce a PDF that is the incorrect size. If not caught prior to submission it will not print as intended.

For Illustrator CS2 and above it is recommended to use the "High Quality Print" preset.

Every file is different and it is not– feasible– to include all possible issues in this FAQ. It is always best to double check your PDF for size and excess white space before uploading.

When using arrows on a double sided sign, special care will need to be taken with the direction of the arrows. If you want the arrows on both sides of the sign to point the same direction when the sign is printed the arrows need to be setup in opposite directions on the production files. It's complicated, we know. See the example illustration below.

• Since there are many types of mounting applications, we do not include mounting hardware with any Mounted Canvas print.

Here is an example of how the gallery wrap will look.

All files should be 8 bits per channel.

With Clear Window Clings, you have the option to use white ink as an overprint so your printed graphic can be opaque in some areas and transparent in others. This will allow for vibrant, crisp color.

Similar to Spot UV masks, White Mask files are separate from your artwork files and black color indicates where the white ink will print.

Make sure to create your mask file the same size as your color art file. This will prevent alignment issues during printing.

Note: White Masks must be made in vector format and be saved as EPS or PDF and use 100% K.

Use vector paths/shapes to create black color areas that will indicate where the white ink base will go. The rest of the area will represent the Clear Window Cling stock.

Black in the White Mask file indicates where white ink will be printed. Remember the following when creating a white mask for your white ink base:

- White ink base will be printed behind any color that’s in your Artwork Layer.
- Areas with color but without a White Mask will be printed with color directly on the material. These areas will have somewhat transparent color due to the Clear substrate.
- Areas with color and a White Mask will be printed as opaque or solid color.
- Areas with a White Mask and no color will be printed as white.
- The black for the White Mask file must be 0% C 0% M 0% Y 100% K or it will not be recognized by preflight.

For further info please visit our Roll Labels FAQ page question #8.

If your Clear Window Cling is intended to be viewed from the outside of a window, please select "Mounted From Inside" when building the product. Also, the artwork should be reversed prior to submission. See images below.

For contour cut orders, two separate files must be uploaded: one regular artwork file, and one cut mask file. The cut mask file must be an all vector, PDF file uploaded at the same time as the artwork file.


We cannot accept any cut mask files that are made using a raster based program (e.g. Photoshop).

• When being cut, the blade will follow the cut mask line you’ve created. It is recommended that you keep your perimeter cut line slightly inside the border of the image you are trying to cut out. This will avoid any obvious edges showing from your background once it is cut.
• Do not use small/thin cut areas, or have perimeter cut lines that are too close together. At least 0.5" must separate your perimeter cut lines from each other. 4over will not reprint any order with perimeter cut lines that are too close to one another.
• Your contour cut line should be a smooth fully closed path. No disconnected lines or open paths will cut. If your cut line is ragged or has any imperfections, they will show up in the final piece

Only one cut per order will be allowed. Please do not add multiple cuts in a single file.

4over will not reprint any order attributed to improper file setup or layout.

Raster based artwork such as photos, or flattened artwork (from Adobe Photoshop) are made up of tiny squares (pixels) and depending on your resolution and/or final output size desired, the file could have a low quality end result. Any raster elements you wish to use should have a high enough resolution (DPI) before considering them for your large format product.

Vector based artwork such as illustrations or clip-art style elements (from Adobe Illustrator) is made with mathematical calculations, and can be scaled up to any size without losing quality. Keep in mind that any effects used in Adobe Illustrator are raster based and have transparency - this greatly adds to file size and you must have correct settings in your "Document Raster Effects Settings" to ensure best output for these effects. If you're doing a photo-quality print on a 36" x 48" poster, and leave the raster effects settings at default 72 DPI - you may see tiny squares in your drop shadows, as opposed to a smooth shadow.

While it is not mandatory, we prefer Adobe formats (such as PDF) - if you're using a program outside of Adobe, it will have to be exported from whichever program is being used as one of the following file types - PDF, JPG, or TIF - prior to uploading.

We only print 4 color process (CMYK). If you use Spot or Pantone colors, please have them converted to process colors prior to uploading your file.

We use #2 grommets, they are 3/8" and brass in color. Grommets are placed in all 4 corners, or Top Corners only. Grommet are placed 1 inch from each corner. Starting point from left to right and top and bottom corners.

In addition to sewn hems, Grand4mat.com also utilizes a hot air welding system that is far stronger than a standard sewn hem, making the need for double hemming a thing of the past.

Files sizes for Grand4mat can be monsterous, chances are your file may take longer than your typical business card file. Your file size and your network connection are the two main factors affecting upload speed. See our Scale & Resolution Example chart at the very top of this faq page.

There are quite a few companies that do just this - convert raster artwork to vector. There are even programs you can buy to accomplish this task. You might want to try a Google search for Raster to Vector art services.

Most printing companies run individual jobs on one sheet. We will utilize the maximum square inch of the sheet by impositioning jobs together dispersing the fixed cost of a job between several projects and then we pass the savings on to you.

When you are done displaying your banner - in order to maximize your future usage, you must keep it clean, dry, and in a dry cool place while it is not in use. Your outdoor vinyl banner will probably get pretty dirty from all the elements during it's time being displayed. The best method of cleaning your outdoor vinyl banner is to lay it flat (if possible) on a clean area, table or floor. It is recommended that you use a mild dishwashing liquid and luke warm water to rinse. Do not use any harsh abrasive or petroleum type cleaners. Clean and dry each side before storing. You must ensure it is completely dry prior to roll up and storage. Any wetness left on the banner will cause mildew and may ruin some of your banner over time.

Once your banner is completely dry - roll it up with the image outward - to avoid any cracking of the printed side. Do not roll your banner super tight or super loose - this will allow for some breathing room while it is stored. Place your banner back in box and store it flat, not vertical. If it is standing up vertically, it may wilt and warp causing wrinkles over time.

2-step H-Stake: Typically used for 24" x 18" and smaller. For signs larger than 24" x 18" we recommend using 2 separate H-Stakes. The wire gauge size used for our H-Stakes is 9 gauge.

We do not colormatch.

Magnets are not always shipped flat, so it is highly recommended to lay them flat on the hood or roof of your car in the sun for a couple of hours before use. This will help evaporate any moisture build-up that accrued during shipment, if any, and it will help your magnets maintain a flat profile. You may want to keep them in a flat box or on a flat surface at all times and only handle them when cleaning and installing, to help maintain their flatness. We recommend you keep your magnets clean on both sides, as well as the placement area on your car door or area of your choosing must also be clean and free of oils, dust, dirt, and other build-up. It's a good idea to take your magnets inside your home or garage away from the elements and lay them flat in a cool dry place, while not in use. You can clean your magnets with a soft moist cotton cloth with water, no abrasive cleaners. It's recommended that you do not stand them up on their side, as they may wilt and might not lay completely flat on the surface of your car door after wilting. These suggestions are to help the longevity of your magnets.

Note: Be sure to remove the magnet once or twice per week, place it inside your home or garage away from weather elements and lay them flat in a cool dry place while not in use so as to avoid problems from excessive heat exposure.

Wall Graphics are best suited for surfaces like walls, desks, laptops, and glass. Before applying, clean the surface area with a damp cloth and allow it to fully dry. If any dirt or dust particles remain, they may stick to the low-tack adhesive and reduce the number of times you can reapply the Wall Graphic.

To clean your Wall Graphic, we recommend using a soft, damp cloth on its non-adhesive side. Do not use soap, or any other abrasive cleaning agent, as it may affect the printed surface.

For outdoor applications or vehicles, please see Adhesives or Window Graphics.

We are not currently using archival media or inks for our prints.

Torquing of stretched canvas may occur to mounted canvas due to climatic changes such as temperature, humidity, or other changing environmental conditions. The stretcher bars are made of wood and are vulnerable to changes in humidity. It is recommended that stretched canvas print be kept in a stable climate controlled environment to minimize torquing. These issues maybe more prevalent in coastal locations and near large bodies of water where temperature and humidity levels are constantly changing.

Depending on size and other production variables your banner may be produced in multiple pieces that are seamed together. This production variable is to our discretion.

Rider signs are 4mm Coroplast and are designed to sit on top, or "ride" the standard coroplast signs using 8" metal rider pins. These rider pins are optional. Just like the regular Coroplast signs, these will have a linear effect due to the corrugated flutes. The inks used are UV Cured (dried).

Bleed: ensure you have .5" on all sides of your artwork, do not add crops.

Blockout Vinyl is an opaque material that will not let sun or any light through it. It is also not transparent when looking at it from the back. It’s heavier and more durable than our 13oz Banner material plus it’s low curl so even if it’s stored in a tube, it will stay smooth when rolled out. Blackout Vinyl is perfect for hanging banners or signs where banner opacity is needed.

Yes, retractable banner stand parts are available in the marketplace category.

Our 2" Pole pockets have approximately 1" circumference and can be used with up to 1" diameter poles. Our 4" Pole pockets have approximately 2" circumference and can be used with up to 2.5" diameter poles.

Grand4mat processes H-stake orders separately from sign orders. Stakes and signs should both arrive on the same day but it is not uncommon for boxes shipped ground to arrive on subsequent days.

4over has multiple production facilities. To see where your order will ship from to plan your shipping method accordingly look in the Print Job Details window when selecting your shipping method after uploading/finalizing your artwork.

Due to the large physical size of Grand4mat's products some orders may have higher than expected shipping charges. Unfortunately there is little Grand4mat can do as we are bound by the limitations set forth by our shipper, in this case UPS.

Go here to view a short video on how to group ship your orders.

All orders that are being grouped ship must:
-Be of the same type of Coroplast Signs or Outdoor Banners.
-Be placed at the same time.
-Maximum quantity per set is 50.
-Be designated for group shipping at the time of the order.
-Be exactly the same quantity.
-Have the same turnaround time.
-Delivered to the same address and contact person.

The turnaround will start at the time of the final approval of all sets within the group. If one part in the group is on hold for any reason (i.e. revised files, QC reprint, etc.) – all parts will be held until the group is complete. Groups cannot be separated to ship any individual set. Group shipping may add one additional day to the production turnaround time. Please see our shipping policy for more information.

Changes to the shipping service or address can be made through the link on the website up to the point of bindery. Groups will be banded or consolidation boxed depending on the product and number of sets in the group.

Example: A Six set group with a 5-7 turnaround placed on Monday.

a) All sets approved on Monday before cut off time – completion date the following Tuesday.
b) Five sets approved on Monday – one set has new files and is approved on Wednesday before cut off time– turnaround starts on Wednesday – completion date will be 7 business days (weekend not included).

Canvas Banners are rolled and shipped in a square tube. Mounted Canvas will ship no more than one per box to avoid damage during shipping.

Polyester Banners are folded neatly and shipped in either bags or cartons (depending on quantity ordered). While these materials are wrinkle-resistant, light ironing with low heat may be required prior to use.

Due to UPS shipping restrictions, banners that exceed 8' (feet) or 96" (inches) in length will be folded for shipping. These measures are implemented to ensure the most competitive shipping rates.

Folding oversized banners for shipping is a common practice among large format printers, carriers are optimizing the cubic space required to move packages, so odd size shipments are becoming more costly to move through their transportation network and conveyor systems. Our shipping team will use their best judgment when it comes to packing and shipping out your supersized banner. These measures are implemented to ensure the most competitive shipping rates.
