Paperback book printing common problem and cause analysis


1. Hot stamping is not strong


Cause Analysis:


(1) Hot stamping temperature and pressure are not enough. If the hot stamping temperature is low, the hot-melt adhesive layer of the electrochemical aluminum cannot be fully melted, the adhesive force of the adhesive is not effectively reduced, and the aluminum foil layer cannot be smoothly peeled off from the polyester base film, so that the electrochemical aluminum cannot be fully oriented. The surface of the hot material is transferred. At this moment, if the hot stamping pressure is not enough, the electrochemical aluminum does not adhere well to the surface of the hot-pressing material, transfer and adhesion, resulting in poor hot stamping.


Solution: Determine the appropriate hot stamping temperature and pressure according to the characteristics of the hot material and the type of electrochemical aluminum used. It is recommended that the hot stamping temperature be controlled at 75 to 120 ° C and the hot stamping pressure be controlled at 25 to 35 kg/cm 2 .


(2) Improper additives are added to the base ink. For the ironing material with a large solid background pattern, in order to prevent adhesion and smudging of the ironing material, an additive such as a paraffin-containing detacking agent and a brightening paste is added to the ink, and the paraffin component in the additive is difficult. Adhesive bonding with the hot-melt adhesive in the aluminum alloy affects the adhesion and adhesion of the electrochemical aluminum on the surface of the substrate, resulting in poor hot stamping.


Solution: After adding the paraffin-containing additive to the underlying ink, the surface of the ink layer can be changed by overprinting the surface of the underlying ink layer with a 991# brightener which is added with 2% white oil. Printability improves the affinity of the ink layer surface with the electrochemical aluminum foil.


2. Hot stamping is not possible


Cause Analysis:


(1) The ink layer on the surface of the ironing object is crystallized. The crystallized ink closes the gap between the paper fibers on the surface of the substrate, hinders the penetration of the anodized aluminum hot melt adhesive into the paper fibers, reduces the adhesion of the electrochemical aluminum on the surface of the substrate, and transfers to the surface of the substrate. The difficulty is increased, resulting in a hot stamping phenomenon.


Solution: It is recommended to use 15# anodized aluminum material with good quality and strong adhesion, or to solve the problem by extending the pressing time by adding a thin and soft pad on the corresponding position on the impression cylinder. However, in order to fundamentally solve the problem of hot stamping, it is necessary to strictly control the amount of red dry oil added to the ink layer on the surface of the substrate during the printing process so as not to exceed 0.5%.


(2) The model of the electrochemical aluminum is not properly selected. There are many types of anodized aluminum, which are mainly distinguished by the fastness and tightness of the anodized aluminum. The performance is the adhesion and peeling degree of the electrochemical aluminum during the hot stamping process. Therefore, different types of anodized aluminum have a suitable ironing. material. Usually, we can use both hands to rub or use a transparent tape to expose the surface of the electrochemical aluminum, and visually measure the difficulty of the color layer falling off to distinguish the fastness and tightness of the electrochemical aluminum. In the case of large-area hot stamping, if the aluminum alloy with high fastness and tightness is selected, it is not easy to peel off and adhere, resulting in the incomplete transfer of the electrochemical aluminum to the surface of the ironing object, thus causing some defects in hot stamping. .


Solution: When printing a large area of the pattern, it is recommended to use anodized aluminum with low fastness, small tightness and easy transfer.
