Abstract

The invention discloses a broken dot matrix jet printing method of a digital inkjet printer. The digital inkjet printer performs printing by distributing dots by a random dot-matrix printing mode rather than the former longitudinal or horizontal random dot distribution rules to a certain extent, that is, a group of dot matrix (nxn, n is the number of dots) are printed instead of one dot, and the dots are randomly printed on a carrier, and the generation mode is random generation. The broken dot matrix jet printing method has the advantages of ensuring adequate printing picture, and avoiding reflection stripes of ink color and ultraviolet solidified ink in each dot distribution which is caused by the same size of the ink dots by virtue of causing the ink dots to form a plurality of dot matrixes.

Description

The broken dot matrix air brushing method of digit inkjet printer

Technical field

The present invention relates to a kind of numerial code spray drawing method, particularly at random a kind of broken dot matrix air brushing method of and the digit inkjet printer that the air brushing quality is high.

Background technology

The digital printing finished as Fig. 1 repeatedly to layout often.

Be the specking range L, be example as if layouting with 4 times, then L is divided into four parts, each stepping (Print direction Y) 1/4th.

At present the digit inkjet printer method for spray-drawing of layouting is generally the method for vertically layouting (as shown in Figure 2), or laterally layouts method (as shown in Figure 3), and schematic diagram is an example with 4 air brushing of layouting.Because positioning accuracy request is too high, the some size is all identical, and dot spacing also must be identical, therefore can produce well-regulated striped in the error range of positioning accuracy, and thread cast-off or moire cause the qualitative flaw of air brushing, and the quality of air brushing figure is descended.

The method of layouting at random of employing recently shown in Fig. 4, adopts each different, method of layouting at random, though this method can effectively reduce the requirement to positioning accuracy, can make the air brushing graphical quality keep stable again.But the method is meticulous at random, and meticulous hour of specking, also can produce moire or can produce the strong reflect light striped in uv curing ink, can not further promote the quality of air brushing figure.

Summary of the invention

Technical problem of the present invention is that a kind of broken dot matrix air brushing method that can further promote the digit inkjet printer of air brushing graphical quality will be provided.

In order to solve above technical problem, the invention provides a kind of broken dot matrix air brushing method of digit inkjet printer, during the dot printing of digit inkjet printer cloth, change original vertical or horizontal more or less regular at random cloth dot printing, but utilize dot lattice printing pattern at random, promptly once printing is not a point, but one group of dot matrix n * n, n counts, and be air brushing at random on carrier, its generate pattern is to produce at random.

Wherein the n size of ordering according to the precision of digit inkjet printer own, select all kinds of UV printing ink of shower nozzle parameter, use to decide.

The n value is little, and precision is higher, reflects responsive to the color of printing ink or the gloss of uv curing ink;

The n value is big, and precise decreasing remedies better the color of printing ink or the gloss of uv curing ink.

N is the cloth dot matrix, but not the repeated use of print data.

When adopting broken dot matrix air brushing method of the present invention, also can insert low amount ink dot, can further improve color density and precision at the achromatic region of n * n dot matrix.

Superior effect of the present invention is: this method is by forming ink dot a plurality of dot matrix general layouts at random, under the condition that guarantees the print screen abundance, the layout ink color of generation and the reflex streak of uv curing ink that cause because of sizes of ink dots is identical have been avoided again at every turn.

The specific embodiment

See also shown in the accompanying drawing, the invention will be further described.

As shown in Figure 5, the invention provides a kind of broken dot matrix air brushing method of digit inkjet printer, during the dot printing of digit inkjet printer cloth, change original vertical or horizontal more or less regular at random cloth dot printing, but utilize dot lattice printing pattern at random, promptly once printing is not a point, but one group of dot matrix n * n, n counts, and be air brushing at random on carrier, its generate pattern is to produce at random.

N is the cloth dot matrix, but not the repeated use of print data.

This broken dot matrix air brushing method is checked after tested: the print quality to fixing point, height shower nozzle is all effective, and black all effective to ultra-violet curing China ink or other.

Claims

1, a kind of broken dot matrix air brushing method of digit inkjet printer is characterized in that:

During the dot printing of digit inkjet printer cloth, change original vertical or horizontal more or less regular at random cloth dot printing, but utilization dot lattice printing pattern at random, promptly once printing is not a point, but one group of dot matrix n * n, n counts, and be air brushing at random on carrier, its generate pattern is to produce at random.
