Offset printing process is relatively mature, especially in tune mesh printing, a set of standardization, data-driven way; However, receipt printing printing in addition to the adjustable printing mesh, it involves a lot of color reproduction, such as the red field of large area, the gold (silver) color, pearl effect, etc.; Because the color especially the request of the field to the color saturation and brightness is higher, and offset printing in the printing field, limited to the ink layer thickness, is not; Can be taken at this time "deep shallow" after the first two printing method, design as far as possible avoid hollow out text field edition, add overprint is difficult to avoid.
Now, because the receipt printed material widely adopt composite paper materials, and the popular printing ink printing, there is adhesion, frictional resistance and dry some problems; Therefore, manufacturers tend to offset press reform in uv skills, basically solved the problems existing in the composite paper printed matter; Because the uv ink has greatly promoted the appearance of ink layer physical function, many packaging printing company has started to take offset printing uv ink printing fine sand, gold, silver and many other popular offset printing can be difficult to achieve the effect.
Gravure due to high saturation, high contrast, high brightness, strong consistency, plate printing endurance higher characteristics become receipt printing printing another optional method; If field larger graphic design draft, request mose, common offset slightly insufficient, adopts the method of intaglio printing, can satisfied requirements; Gravure another advantage is can print other substrates other than the paper, for example on the laser anti-counterfeiting film printing first, again with cardboard in compound, to another kind of visual effect, etc.
Shades of receipt because gravure printing in the field, and the line is in the majority, so in the process of the request of the color management is not strict, relatively moderate compared to offset printing, printing process flexible printing is comparatively easy.
Silk screen printing of grind arenaceous, refraction, ice, wrinkles and other artistic effect which makes the wine box packaging, greatly aroused the consumer's purchase desire; Other, because to the brightness of the screen after local uv glazing products add, stereo sense is strong, is often used on receipt printing color box groom; Flexible printing is now rarely used in receipt printing color box printing, there are a lot of beer label will adopt this kind of printing method; Rely on its environmental and health advantages, will gradually be recognised by the winery and favor.
