The substrate is not solid ink printing causes and Solutions

Printing materials for printing, it is important to print in the printing materials before the strict degreasing and pre-treatment inspection. When the substrate surface adhesion grease, binder, dust and other substances, will cause ink and substrate bonding bad. Plastic products before printing surface treatment is not sufficient will cause failure of ink fixing fragile.

The shares as polyethylene printing material, in order to improve the adhesive performance and ink in printing, must be surface flame treatment, such as metal materials must be degreased, dust processing before printing, printing after drying should be handled in accordance with the requirements of the ink drying temperature, if handled properly will produce ink film stripping fault. In addition, in textile printing in order to make textiles waterproof, generally have to silicon processing, so printing is not prone to ink adhesion phenomenon.

Glass and ceramics and the like, after printing to high-temperature sintering, so long as the appropriate temperature treatment will be good adhesion. The ink film fixing fastness good and bad simple method: when the object to be printed is paper, the printing surface of the ink at the crease repeated bending is stripped, if ink stripping, so it has weak bond strength. In addition, the print is exposed to rain, see whether ink easily, this is also a way to test the quality of the ink film fixing fastness.

The ink itself is not enough to cause the ink film adhesion fixing fragile, the best replacement of other types of ink for printing. Dilution solvent improper selection will also appear ink fixing fragile phenomenon, in the selection of good solvent to consider the nature of the ink, in order to avoid the occurrence of ink and substrate bonding phenomenon is not strong.
