絲網(wǎng)印刷可按其版式、印機(jī)品種、油墨性質(zhì)及承印物的類型分成很多種，但就其印刷方式可分為下面幾種。
4. 間接絲網(wǎng)印刷:前面3種方法都由印版直接對(duì)承印物進(jìn)行印刷，但只能印一些規(guī)則的幾何形體，如平面、圓柱面、圓錐面等，對(duì)于外形復(fù)雜、帶棱角及凹陷面等異形物體，則必須用間接絲網(wǎng)印刷的方法來(lái)印，其工藝常由兩個(gè)部分組成:平面絲網(wǎng)印刷和轉(zhuǎn)印，即絲網(wǎng)印刷圖像不直接印在承印物上，而先印在平面材料上，再用一定方法轉(zhuǎn)印到承印物上。間接印刷的其中一種方法如，先用平面絲網(wǎng)印刷法在平面玻璃上印出圖像，再用富有彈性的硅膠頭，如同蓋章似的從玻璃板上吸取油墨圖像，然后移印到異形面上:間接絲網(wǎng)印刷的另一種類方法是花紙轉(zhuǎn)印，如:絲網(wǎng)印刷花紙+熱轉(zhuǎn)印、絲網(wǎng)印刷花紙+壓敏轉(zhuǎn)印、絲網(wǎng)印刷花紙+溶劑活化轉(zhuǎn)印。間接絲網(wǎng)印刷已成為印刷行業(yè)的主要領(lǐng)域。
Screen printing and printing machine varieties according to the format, the nature of the ink, and the type of substrates is divided into a lot of kinds, but in the way of printing can be divided into the following several.
Flat screen print screen printing: flat screen flat screen printing machine is to use graphic way of printing, silk screen version on planar substrates, printing, plate fixation, scraping version of the mobile.
2. The flat screen surface screen printing, screen printing flat screen surface is flat screen plate in curved substrates (e.g., ball, cylinder, cylinder, etc.) on the method of printing. Fixed when printing, scraping board, plate along the horizontal direction, substrates with plate rotation.
3. The cylinder screen printing: cylinder cylinder screen printing is silk screen version, cylinder fitted with fixed scraping board, drum plate and substrates for synchronization line speed mobile printing method.

4. Indirect silk screen printing: in front of the three methods are directly by the plate printing on substrates, but only some of the rules of geometric, such as plane, cylinder, cone surface, for complex shape, deformed objects, such as edges and concave surface must use indirect silk screen printing method to print, the process often consists of two parts: flat screen printing and transfer printing, the screen printing image is printed directly on the substrates, and jump on the flat material, then use a certain method of transfer printing on substrates. Indirect printing as one of the methods, with flat screen printing method first printed image on the flat glass, with a flexible silicone head, like a sealed ink image from the glass, then pad printing to the special-shaped surface: indirect screen printing another kind of method is wire transfer printing, such as: silk screen printing, hot stamping, silk screen printing color paper and paper flowers pressure-sensitive transfer printing, silk screen printing color paper + solvent activation transfer printing. Indirect screen printing has become a main area of the printing industry.
