1. Udskrivning af standard lyskilde er meget vigtig
At present, many self-adhesive label printing companies do not use printing standard lighting sources, which poses a hidden danger to the color consistency control of label products. Many self-adhesive label printing companies use the lighting source to see the color during the night shift is very different from the color seen in the sunlight during the day, which leads to the difference in printing color.

Spot color inks are prepared from a variety of primary color inks, and most UV Blæk er pantone (pantone) farvesystemer, så når vi formulerer pletfarve blæk, formulerer vi ofte i henhold til forholdet, der er angivet på Pantone -farvekortet ., men det skal påpeges her, at blækforholdet på Pantone -farvekortet ikke nødvendigvis er helt nøjagtige, og der er ofte små forskelle .} the printing staff to the ink color is very important. Printing staff should learn more and practice more, and accumulate experience in this area in order to achieve the level of proficiency.

There is a situation: after the label product is placed at the customer's place for a period of time, its ink color gradually changes (mainly manifested as fading), but the same phenomenon does not occur in the previous batches of products. This is generally caused by the use of expired ink. The shelf life of ordinary UV ink is usually one year, and the use of expired ink is prone to fading Derfor skal selvklæbende etiketprintfirma proces .
