Silk screen printing and other printing way what is the main difference between ?
? silk screen printing and other printing methods compared with the main difference has the following several ?
1) adaptable flat printing, letterpress printing, gravure printing method normally only for printing on flat substrates.Printing and silk screen printing can not only in the plane ? in curved surface, spherical and concave and convex surface printing on substrates.On the other hand ? silk screen printing not only in hard surface ? can also be printed on the soft material ? is not restricted by the quality of a material of substrates.Besides ? screen printing in addition to direct printing ? can according to need to adopt indirect printing method ? the use silk screen printing on the gelatin or silicone version first ? then transfer to the substrates.Therefore screen printing resilient ? the wide range of applications.
(2) the ink layer thick ? stereo sense is strong ? rich texture of offset printing and embossed ? gravure ink layer thickness is commonly 5 microns to 12 microns flexible (aniline) ? ? printing ink layer thickness of 10 microns and silk screen printing ink layer thickness is far more than the ink layer thickness ? generally up to 30 microns.Specially printed circuit board with thick silk screen printing ? ink layer thickness to 1000 microns.With foam foam ink printing braille point yu ? ink layer thickness is 300 microns.Silk screen printing ink layer thick ? prints rich texture ? stereo sense is strong ?
This is the other printing method can not be compared.Silk screen printing not only can be matching color and monochrome printing ? can also add color printing.
(3) strong light fastness ? bright color with silk screen printing has the characteristics of bearing ? ? so it can be used to all kinds of printing ink and coating not only can use the slurry, bonding agent and various pigments ? can also use coarser particles of paint.Besides ? screen printing ink mixing method is simple ? ?, for example can be straight light paint
Pick up into the ink mixing ? this is the another big characteristic of silk screen printing.Screen printing products with strong light fastness of great advantage.By the practice that ? according to the use of black ink in coated paper last time stamping after comparing measured maximum density range ? offset printing, embossed for 1.4 to 1.6, 1.8 ? gravure and screen printing of maximum density range can be up to 2.0 ? packaging design market positioning should be how to do so the light fastness of silk screen printing products than other kinds of printing products of strong light fastness ? is more suitable for the outdoor advertising, signs.
(4) printing area is big general offset printing, letterpress printing methods, such as the printing area size sheet maximum size more than sheet size ? ? is limited to the mechanical equipment.And silk screen printing can be the most widespread ? the current printing screen printing products greatly up to 3 m x 4 m ? is even greater.More than four points are the difference between silk screen printing and other printing ? characteristics and advantages of screen printing as well.To understand the characteristics of the silk screen printing ? ? on the selection of printing method can foster strengths and circumvent weaknesses ? highlight the advantages of screen printing ? to achieve more ideal printing effect.
