Most metals receive a base coat of enamel (or occasionally paint), which is baked on. Printing then takes place on the enamel coating by offset lithography, dry offset letterpress, and occasionally other processes. 

In applications where the pigment is fast enough to solvents to satisfy the requirements, it may also be used for offset, packaging gravure, and flexo printing inks. The resulting prints are soap, alkali, and acid resistant. They are not completely fast to paraffin and quite sensitive to butter and a number of other fats. P.R.14 prints are not fast to clear lacquer coatings and may not be sterilized. Heat stabil-... 

P.O.62 is frequently used in the printing inks field to produce lightfast offset and aqueous flexographic inks. Its lightfastness in these media equals step 5 to step 6 on the Blue Scale, depending on the standard depth of shade. The prints are not completely fast to alkali and do not tolerate clear lacquer coatings and sterilization. 

Generally coated sheets have higher gloss and will print better if the surface fibers have been laid and do not come out on the offset blanket. 

This method is used for curing coatings and inks on plastic cups, tubs, tubes, or metal cans. The parts are placed on mandrels, which are attached to a rotating device. This device moves them through the individual stations feed, pretreat (most frequently corona or flame, for plastics), printing, curing, and take-off. The printing is done by dry offset (see Section 7.5.3).
