Protruding imprints in the label that prevent bogus to presswork the application of the domain

In last few years, homePrinting ink of ability in swimmingPressworking industry, be in especiallyFood is packed, Plastic presswork, soft edition pressworks waited for a respect to have rapidder development, but in gravure, especially paperboard kind smoke mark pressworks the domain has some of lag relatively.
1, manufacturing efficiency and presswork cost
The printer foreword that protruding imprints and hind treatment working procedure produces even the line the situation more, can implementation and offset print, sunken imprint, the net imprints, digital gush code presswork means, and cold very hot, model cuts those who wait for treatment device to join even group, the production that is label from cast expect model to cut finished product to finish offer possibility, manufacturing efficiency is tall, presswork cost is low. And odd label of piece of paper offset print is general it is to presswork first, chase piece of treatment to become finished product again next, accordingly, production is periodic and longer, presswork accordingly cost wants a few taller.
2, dry speed and dry effect
Pressworking on the spot when, protruding imprints aircraft is general use UV solidify means, this kind of means is dry speed is fast, dry the effect is good. Be like the printing machine of satellitic type cycle of the sun, each presswork baseplate deserves to have unit of solidify of a group of UV, pressworking when large area is on-the-spot, operation personnel can estimate Chinese ink a little bit shift is big, such pressworking the Chinese ink layer that come out is thick, have qualitative feeling. And common sheet piece paper offset press does not have UV solidify function, the printing ink after pressworking cannot immediately dry, pressworking so when large area is on-the-spot, if Chinese ink layer is thicker, cause easily stick dirty, printing ink dry and undesirable wait for a phenomenon.
3, mesh attune pressworks
When mesh attune pressworks, offset print is behaved relatively outstandingly, arrive from plain net absolutely the transition of the net changes natural; And the performance that protruding imprints is poorer, transfer from plain net absolutely when the net, it is 3% place to be able to appear in site area rate about net phenomenon. Nevertheless, imprint as protruding the advance rapidly of technology of direct plate making, protruding imprints realized site area to lead from 1% ~ the net does not appear inside 99% limits.
4, glue face pressworks
Glue face pressworks is protruding imprints a when the technology has relatively special presswork means, and at present, offset press has not involved type of this one party. Alleged glue face pressworks, when pressworking namely come off the copy paper of stuff of not dry glue first, next in the “ glue that contains glue sticky agent face ” undertakes pressworking, again copy paper to it compound, continue to presswork on the face capable person that doing glue stuff finally and make finished product. This kind pressworks the technical demand of means is higher, and should imprint in protruding go up how to imprint of the back functional aircrew. General, glue face pressworks is to imprint first ” of “ glue surface imprints again the front, because this should imprint protruding,before a few aircrew of machine change this costume or dress to carry offset print on the back to brush aircrew. Additional, the overprint when noticing to carrying two sides on the back to presswork even, presswork the problem such as flatness of pressure control, material.
5, the effect that prevent bogus
Protruding imprints imprint with the net, sunken imprint, offset print presswork the printing machine that means random assembles, can come true to get on a variety of pressworking in a label the advantage between craft is complementary, make label more elegant, have the sex that prevent bogus more. The author thinks, use the label that combined-type printing machine prints, imitated difficulty is quite big. If make a holiday person want to use onefold presswork means will forge the label that prints by assorted printing machine, must have handled 2 times so track an issue, can appear otherwise overprint error, cannot undertake emersion to former label.
By afore-mentioned comparison visible, use protruding to imprint means pressworks the ticket that prevent bogus has definite advantage. And the fact also is such, code, 2 safeguard are contained on market at present code, the label preventing bogus of form code imprints with protruding be in the majority.
