Several kinds of new technology of printing of concern

Published£º2015/5/7

A HYBRID technology application
 
1. Water-based light oil HYBRID technology
 
Water-borne light oil HYBRID technology refers to the same printing can print last presents the highlights and matte two glazing effect of technology. The technology of hardware demand is higher, operation technology and application technology is simple: substrate must be high gloss paper. Printing equipment must be at least 5 + 1 or equipment; Use oily dumb light oil on the final color set by local glazing, PS version along with highlights on the water-borne light oil in the glazing color group full version of glazing, pay attention to the oily matte oil and water-based specular light oil is a special light oil, not ordinary light oil; By adjusting the oily dumb light oil coating weight to control the contrast of light and matte effect;
 
2. UV light oil HYBRID technology
 
UV light oil HYBRID technology is the use of UV light oil on a printing or printing technology can appear the following two effects: a: branch lines and highlights the effect; 2: matte and glossy effect; UV light oil HYBRID technology and water-borne light oil to the requirement of printing hardware HYBRID technology, need to be in high gloss paper printing, need more than 5 + 1 printing equipment at the same time, operation are similar, but dry way for UV curing dry, higher hardware requirements; Adjust branch grain and high contrast effect and adjust the inferior smooth to high contrast effect are through to the oily UV light oil on the ink quantity adjustment done, please note that UV light oil dry problem, in order to ensure the dry UV light oil can decrease the printing speed, specific speed in dry condition decision; Please note at the same time, the complete branch lines and high effect of branch lines effect oily light oil and high gloss UV light oil is used with special light oil; Finished matte and glossy effect of dumb light oil and UV light oil is used with special light oil;
 
2. Suede light oil and metal light oil
 
According to the characteristics of the modern printing, environmental protection and security effectiveness, on the basis of water-borne light oil and add some special effects of water-borne light oil, which has high use value is water-based suede light oil and metal light oil. Water suede light oil is the use of waterborne glazing system in the process of drying after glazing coating appears as the effect of suede, suede and polish on the strength of the effect of light oil, if you use ceramic anilox roller glazing system, through the line number of anilox roll adjustment to achieve the purpose of changing oil quantity, in order to increase or decrease suede effect; Water-based metal light oil is the use of waterborne glazing system after glazing coating surface is metal color, the color has many kinds, including silver, bright gold, bronze, gold and so on the many kinds of color, its is related with glazing, mainly on the strength of the metallic coating and the greater the amount of metal polishing.
 
3. MFX technology application
MFX technology is a kind of common use five-color printing can print a variety of color metal effect, including metal color transition layers of complex metal color, ordinary printing method for various metal color generally adopt color printing ink, one by one the way to solve, but for the level of transfer printing effect is not ideal, the use of MFX technology printing metal color effect is very ideal.
 
Printing substrate requirement Gao Liangguang base material, such as coated paper base material; Five-color printing ink as silver, yellow, taste, green, black, one silver ink requires high brightness, surface combining ability; Four color printing ink needs high brightness, saturation, and transparency; Color sequence is silver, black, blue, red, yellow, use wet wet way printing pressure, this transition metal color effect and the liquidity effect is better; Printing speed is 5000-5000 / hour.
 
4. Pearl application technology
 
Bead light material as improve product added value and high brightness material is used in the printing industry effect is good, it can increase the degree of product colour and lustre bright-coloured, can change color color effect, is a new kind of materials used in packaging and printing, color printing.
 
Pearl materials mainly divided into the following categories:
 
1. Pearl powder, pearl powder is divided into ordinary pearl powder materials and the use of soft resin dispersed pearl ball, color are mainly silver, bright gold, metal, such as colour, interference color rainbow and chameleon series of pearl powder and used according to the direction and the effect is distinguished by different particle size, the smaller the particle size, pearl powder, the stronger the hiding power; The stronger the powder particle size, the greater the pearl luster; Have more strict requirements in the particle size of the printing industry, small particle size can be used to offset printing, the larger diameter can be used for flexo and gravure, and has a better effect.
 
2. The bead light pulp: pearl plasma is a kind of high viscosity, viscosity of bead light material, more suitable for mixed with offset printing ink, has excellent hiding power and good gloss, suitable for offset printing.
 
In use of bead light material, has the following methods: 1. The smaller particle size of pearl powder in offset printing and printing ink printing after mixed in certain proportion; Or use water, UV glazing system in glazing glazing oil adding a certain proportion of pearl powder of glazing coating, effect is better; Pearly slurry mixed with the proportional offset printing ink to printing ink can be larger improved brightness as well as on the effect; 2. The selection and gravure and flexography plate plate corresponding to the particle size of pearl powder mixed with the ink to use; 3. The pearl effect with this kind of ink about bearing capacity and mixing ratio of pearl;
 
5. Avoid alcohol (IPA) education version fluid
 
In order to reduce alcohol consumption in the production printing and improve printing quality, use free liquid alcohol education version has become a trend, for this kind of situation, a VARN of new free liquid alcohol education version solved this problem.
Education version fluid additives: 3-5%; Isopropyl alcohol content: 0-6%; Regard education version of liquid and press water way, the production process does not need to continue to add; In the use of free liquid alcohol education version is should pay attention to because of the water system adaptability to embellish version of fluid and operating habits, suggest we do to reduce alcohol first, after a period of time, then do it free of alcohol; Pay attention to when using free alcohol education version liquid presses the original water roll containing hydrophilic substances, can be used directly from liquid alcohol education version of water roll, but if to replace the original water roll, not containing hydrophilic substances, will affect the liquid alcohol education version of the free use.
