    • What type of files can I send to sellers?

    • We recommend saving as a .PDF. You may also send the file in the following types: jpg, jpeg, tif, tiff, eps, and png.We prefer that you send .PDF with embedded or outlined fonts. .PDF's are easier to handle and will likely speed up your turn-around. Remember to add 0.125" to the edges (no black marks or borders) and flatten your files before uploading.
    • How to avoid transparency issues?
    • Never use shadows, glows, or any other transparency (image or otherwise) on top of a spot color. Always convert your spot color to CMYK and flatten before sending.
    • What is overprinting, and how can it ruin my order?
    • Overprinting refers to the process of printing one color on top of another.
      Unexpected results may occur if you have accidentally set certain objects to overprinting. Always check logos and other artwork before submitting.
    • Files for Spot UV orders
    • When creating a Spot UV files, please create separate Spot UV file  to show where the UV will be placed.
      Use 100% K to indicate where you would like the UV. White will indicate no UV.

    • How to avoid blues do not come out purple after printing?
    • Blue is close to purple in the CMYK spectrum.
      To make your blue color look less magenta after printing always make sure to leave at least a 30% difference in your Cyan and Magenta values. Remember, use a low amount of magenta whenever using high amounts of cyan to avoid purple.

    • How do I export a .pdf correctly?
    • When exporting from any program such as Indesign or Illustrator, use these settings to make sure your .PDF files export correctly.


      • Adobe PDF Preset is set to: Press Quality
      • Compatibility is set to: Acrobat 4 (PDF 1.3)
      • Compress Text and Line Art is set to: Off
    • Printing black and white in full color CMYK
    • Printing grayscale always check the CMYK values in the final document. If there are values other than K in your grayscale image, there is a chance that the color will vary.To eliminate all values other than K, use your Channel Mixer (adjustment layer) in Photoshop, then click "Monochrome" and adjust accordingly.

    • How to print rich black?
    • If you print black alone as 100% K, the resulting black may not be as dark as you might like.
      We recommend using C 60; M 40; Y 40; K 100
      This will give you a deep, dark, rich black.

    • How to avoid the cracking edges?
    • Cracking of the edges sometimes occurs when the design contains dark colors. To prevent this, use lighter colors or if you must use dark colors, use as little dark ink as possible.
      Cracking is normal when coated jobs are scored and folded. Ordering the job without UV will help but may not prevent this. As the job is used and folded more and more, cracking will eventually happen.

    • What is gradient banding?
    • If you use a gradient, check your digital files for gradient banding - make sure it has enough room for a smooth transition.

    • How can Pantone colors affect the way my job prints?
    • Convert all your Pantone colors into CMYK before submitting your order.
      Effects, such as shadows, glows, or transparency on top of your Pantone colors will look different on screen and after printing:

      Pantone issues after printing

      transparency issues

      You can see the image is no longer transparent on top of the Pantone color. These white areas will show up during printing. To fix this issue, convert all your Pantone colors into CMYK.

      If you need to have a Pantone color in your art, for example when doing a silver 877c job, you must create a clipping mask around the image so the white area will not show up. This must be done before submitting the order.
    • Files for Spot AQ orders
    • When creating a Spot AQ files, please create separate Spot AQ file  to show where the AQ will be placed. 

      Use white, 0C 0M 0Y 0K, to indicate where you would like the AQ. Black, 100%K, will indicate no AQ.

    • How to set up files for Foil orders?
    • When uploading files for Foil orders, please create separate Foil mask file  to show where the Foil will be placed.
      Use 100% K to indicate where you would like the Foil. White will indicate no Foil.
      If order contains foil and UV spot - please provide separate files for Foil and Spot masks.
      The mask can only be black and white. All black areas should be 100k or only 100% black with no other colors added.

      Please keep in mind that the Foil and UV can't overlap.

    • Multipage booklets files
    • Rules to follow when creating your Multipage booklet:

      • Page counts start on the cover as page 1, inside cover as page 2 and so on.
      • Total bleed is .25” and total Safety is .5”. For example, an 8.5x11 booklet with bleed should be 8.75x11.25 total. 
      • Only single pages will be accepted. NO readers OR printers spreads.
      •  PDF files are preferred but single page files are also ok.

      Artwork done in Indesign or other layout software as spreads or facing pages must be saved out as single page pdfs. When creating your design, keep this in mind especially when doing crossovers. The easiest way is to create the bleed is when creating your document. Below are instructions on how to create your document in Indesign.When creating your document, make your page size the cut size and your margin size .25” for safety for a .5” total:

      Then, click the More Options button on the right. It will reveal Bleed and Slug settings below. Enter .125” as the bleed for a total of .25”:

      Your Indesign document is now ready for proper booklet layout. You should see proper bleed and safety guidelines:

      When your ready to export your booklet as PDF, make sure to Use Document Bleed Settings in the Marks and Bleeds menu:

    • Will I see the proof of my artwork before printing?
    • Yes. Each seller can send you electronic approval before production starts. Please set "Electronic Approval" requirement in your cart while processing your order. You can also order hard copy proof of your order from your seller. 
    • What color mode should my files be?
    • CMYK color mode. RGB files appear brighter on the screen, but once printed colors may look dull, desaturated or shifted and you may not be satisfied with the result. 

    • How should i set up my bleed and crop marks?
    • It is very difficult to print exactly to the edge of a sheet of paper, so it is necessary to print a slightly larger area than is needed and then trim the paper down to the required finished size. Images, background images and fills which are intended to extend to the edge of the page must be extended 0.125" beyond the trim line.

      When sending an .eps or .pdf, make sure you include crop marks so the job could be cut correctly.
