Printer’s Marks and Bleed Areas
I find that I am still lacking in the terminology of printing and why I should get into the habit of using printer’s marks and bleed areas. They help the printer to line up and make sure that the print is running properly and make sure that mistakes are kept to a minimum. They determine where to trim the paper after printing, align separation films when producing proofs, measure film for correct calibration and dot density, and allow colour consistency within a print run.
Printer’s marks including -
- Crop marks that add cross hairs in each corner that determine where the page is to trim it.
- Bleed marks add lines that define the amount of extra space outside the page size that show how far you should extend your artwork of the page.
- Registration marks add small targets outside the page area that the printer can align different separations to in a colour document
- Colour bars add small squares of colour representing CMYK tints and grey tints that the printer follows for colour consistency
These marks are used for all manner of different areas of printing, from the beginning, making sure your print is lined up correctly through to colour consistency and the finishing of the job, aligning and trimming.
