Because our presses print using Cyan, Magenta, Yellow, and Black (CMYK) inks, all elements of the design, including any linked images, must be in CMYK (Process) mode prior to sending your artwork. Please note, this can cause significant shifts in color; we recommend you allow time to carefully review and do any necessary color corrections before sending us the files.
When you’re creating artwork files, you have a choice in color profiles for your design. RGB (Red, Green, Blue) is used for screen display, like websites. CMYK (Cyan, Magenta, Yellow, Black) is what’s generally used in physical printed objects, like the bags and pouches that come off our presses. It’s important your artwork files are set up in CMYK format at the beginning of your design process so what you see on screen most closely matches what will actually come off the press. Files produced in RGB mode may produce unwanted color shift and disappointing results, as many bright values seen on screen cannot be reproduced in print.
