What is the difference between screen printing ink and lithographic printing ink?

Main differences between screen printing blending oil and lithography blending oil;

1, the two systems are different, and the application methods are different; Screen ink mixed with oil binder, such as epoxy modified acrylic acid and polyurethane; The binders of offset printing ink are Panasonic modified phenolic resin, linseed oil, soybean oil, gum oil and other vegetable oils.

2. Silk-screen printing ink blending oil is used to dilute silk-screen printing color ink, adjust fluidity and improve printing effect; Lithographic offset printing ink mixed oil is only used as diluent.

3. Toilet water can be added to screen printing ink blending oil for dilution, but toilet water cannot be added to offset printing ink blending oil.

5. The development direction of screen printing ink blending oil is to change from oily hydrotropism, which has been realized; The development direction of offset printing ink blending oil is to change from non-environmental aromatic oil to environmental protection vegetable oil oil, which has also been realized.

Summary: Screen printing and offset printing are two different things, which cannot be compared, let alone universal.
