This article relates to printing processes; for overprints on stamps or currency see Overprint

Overprinting refers to the process of printing one colour on top of another in reprographics. This is closely linked to the reprographic technique of 'trapping'. It is also the term used in the production of envelopes customised to order by printing images (such as logos) and texts (such as slogans) on mass-produced machine-made envelopes; the alternative way of producing such envelopes is to print "on the flat" and then cut out the individual shapes and fold them to form the envelopes.^{[citation needed]} However the latter method is generally only economically viable for large print runs offering returns to scale.^{[citation needed]}
