Frequently asked questions
Can I invert the colours — light pattern on dark?
Some scanners handle it and many do not. If you must, test extensively across devices before printing a run.
Which colour combinations fail most often?
Low-contrast pairings such as mid-blue on mid-green, and any light foreground. Keep the pattern dark and the background light.
Does colour affect print?
Yes. Convert to CMYK and proof it — colours that look fine on screen can lose contrast on press.
