Make sure that the individual perforation lines run parallel to the edge and to each other. Perforation lines cannot cross each other.

Make sure to keep a safety margin of at least 3 mm between the perforation lines and the edge.

During the production of paper products, cutting imperfections are to be expected - cutting can be off by a couple of millimeters from the cutting line. To allow leeway for such imperfections, you should add 3 mm of bleed on all edges of your artwork. Make sure that all colors, background pictures, and elements extend to the edge of the bleed area, to avoid the appearance of while borders on certain edges after cutting. Learn more how to set up the bleed here.

To ensure that no important elements (text, graphics, images) get cut off from your paper product, make sure to keep such elements at least 3 mm away from the edge of your finished product dimensions.Click here to know how to set up 3 mm safety margin.

Except for silkscreen and pad printing, files should be prepared in CMYK color mode. Keep in mind that if the setup is wrong, colors on the finished product may differ from the file you sent. Here is how to set your artwork to CMYK color mode in Adobe Illustrator.

To avoid blurriness, use only images and graphics that have a resolution of 300 DPI or more. Before sending your files, make sure to embed your images into the file. Read more about how to check the resolution of your assets.

When setting up grey elements, set K to a percentage between 0 and 100, and keep all other colors (C, M, and Y) equal to 0%.

When setting up black text, thin lines and small elements, use pure black, i.e. C = 0, M = 0, Y = 0, K = 100). Text, thin lines, and small elements in pure black color should be set to overprint to avoid white gaps around the text. For larger elements, use a composite form of black (we recommend C = 30, M = 0, Y = 0, K = 100).

If lines are 2 pt thick or less, use only 1 or 2 colors. 4 colors may be used for thicker lines.

To avoid issues with fonts when submitting your file(s), make sure to convert fonts to outlines, or to embed all fonts when saving to PDF.

The best format for submitting print-ready files is PDF, under the PDF/X-1a standard. Where possible, submit your files in PDF format. See why PDF/X-1a is the right format for printing.

Make sure that no elements are set on overprint, unless you need them to be.
