how to inspect the appearance of the non-drying label: to check whether there is burrs self-adhesive materials
drum pressure sensitive material is bright and clean, no damage, is the basis of ensure the quality of the adhesive label printing, so the printing process must be carefully checked before the cutting edge of the reel stickers materials for burrs, whether the damaged due to improper storage and transportation, and will reel stickers material volume 4 & ndash; Five laps, carefully check the cutting edge.
check whether there is a crack on self-adhesive materials
self-adhesive materials in cutting, if the cutting tool adjustment is not appropriate or not enough sharp edge, in the face of the adhesive material, cracks on the bottom of the paper or paper, pull crack in fiber and adhesive stick. The occurrence of cracks may be continuous, also may be random, may appear on one side of the drum adhesive materials, may have on both sides, so the adhesive material in front of the computer printing, variable closely examine the bottom paper and whether there is a small crack on the paper.
then, take a pass the inspection of samples, strip on the bottom paper again check whether there is a crack in a paper and bottom paper below, because crack is sometimes very small, can only be found after separated at the end of paper and paper. It is important to note that due to the printing ink and adhesive will gradually accumulated in the process of printing on the paper guide roller printing machine, can also cause cracks on the edge of adhesive materials. So, even if have begun to printing, also can't suddenly the above problems.
check whether edge of adhesive material adhesion, whether the bottom paper coated silicon leakage
rim adhesion or bottom paper self-adhesive materials parts with silicone oil leakage, in the process of printing will cause surface when the waste paper, can't normal production. So, want to take a long 1 meter or so before printing adhesive material, strip away with the hand, take a look at the edge or other parts have not smooth uniform strip away.
check the reel stickers material cutting end is straight, the tightness of rewinding is uniform
if the reel stickers material cutting face not neat, not only affects the alignment when printing, but also waste arising from die cutting position change difficulties; The tightness of rewinding when inconsistent will cause printing paper tension changes, uneven tension will cause the same printing quality problems.
