1、织物丝印的定位及套准知识介绍Introduction of positioning and registration knowledge of silk screen printingIntroduction to localization and registration knowledge of fabric silk screen12-16 China printing networkThe process of patterning a dye or coating on a fabric is called fabric screen printing. With the rapid

2、 development of printing technology, foam printing, printing, printing, fluorescent luminous pearl printing, printing, transformation effect of anodized aluminum transfer printing, electrostatic flocking transfer printing fabric special printing technology has been developed, the application scope o

3、f the fabric is more broad. All kinds of colorful fabrics are more practical and have certain artistic appreciation.However, in order to obtain an ideal fabric silk screen that meets the design requirements, besides the reasonable selection and deployment of printing materials, the orientation and a

4、lignment of the fabric must be paid attention to during the printing. Because of its soft texture, the fabric has a great influence on the location and overprinting accuracy of silk screen. The location and registration of fabric silk screen are introduced (suitable for hand screen printing).First,

5、silk screen positioning methodThere are two kinds of screen printing methods: one is fixed screen, substrate moving. Another is screen movement (running version), fixed substrate. There are many ways to locate it;1. patron lawFor a certain thickness, the edge of the substrate neatly, you can put its

6、 two vertical and horizontal side of the operating platform fixed anchor positioning.2. hole methodFor the substrate with holes, 2-3 holes can be identified as the positioning holes, and they are fixed on the nail fixed on the operating table (the nail height is lower than the substrate thickness).3

7、. illumination methodThe operating table is made of light transmitting material, such as glass, and the following is provided with light. For a substrate with a certain transmittance, depending on the light, so that the substrate on the substrate and the operation of the base line coincide, position

8、ing, overprinter.4. inhalationFor small or thin substrate, the operation table of the suction suction holes suck and positioning.5. bond methodThe operation platform is coated with adhesive, and the substrate can be stuck, and the method is used for positioning.6. platen methodThrough the screen mob

9、ile (run version) were fixed on the first screen, printing out operation table on the long hole on the screen, the rules match (insert)Two, fabric silk screen positioning1, for a small area with a certain thickness and hardness of the fabric, such as clothing, hat, uppers, trademark bag piece can be

10、 used on positioning method. If the substrate is too soft, without affecting the effect of silk screen and the use of silk screen, the substrate can be sizing, so that very scraping to locate.2, for clothing, sheet materials, sheets, towels, pillowcases, quilt cover, curtains, tablecloths and other

11、large fabric printing, printing and soft, using the table method, positioning (running version), silk screen is appropriate.Three. Table positioningStructure of 1. bedplateThe bedplate is mounted on wooden, iron or cement block, with a height of about 0.7 meters. The top is lined with artificial lea

12、ther, smooth and tight, without seams. Artificial leather mat with cotton blanket, which has certain elasticity. Custom holes are provided on the upper side of the table. A water tank is arranged at the two sides of the advanced operation bedplate, and a drain pipe is arranged at the end of the bedp

13、late for washing the bedplate with water at the end of the screen printing.The length of the platen depends on the area of the substrate, the quantity, the drying speed of the printing material, the number of overprinting, the production conditions and so on. The long platen is over 100 meters. Plat

14、en length facilitates overprinting to mass production. If it is limited by the length of the workshop, a few short bedplate can be used to solve it.In order to improve the utilization ratio of the bedplate, especially for overprinting, the indirect steam pipe or electric heating tube is installed un

15、der the table surface so that the temperature of the table can be kept at about 45 DEG C, which is often referred to as the hot plate screen printing. Usually, a cold platen is not heated. Special printing on the hot platen screen printing, we must pay attention to the final silk screen effect.Struc

16、ture of 2. net frameThe screen frame of silk fabric is made of wood or iron. As the aluminum alloy profile pipe network frame has the advantages of light weight, firm and easy corrosion, it has been widely used.The fabric screen screen frame is the same as other screen printing frames. Only on the s

17、ide of the box, the upper end is about 2 cm from the horizontal frame. There are two threaded holes (5 cm apart) that can screw 6 cm (or 8 cm) screws (the length of the screws to be inserted into the platen, Kong Weiyi). The lower end of the same side of the net frame is correspondingly provided wit

18、h two threaded holes. Screw on the four screws can be used as a net frame rules, making the screen can be turned down, when the screen spinning again, very convenient.3. fabric fixation on platenA method of the single piece of fabric (the area is not too large) around the adhesive tape glued on the

19、platen. Another method is commonly used on the platen brush a layer of water soluble (starch) slurry, the fabric flattening in the operating table, the cement.Four, overprinter accuracyFabric flattening, glued on the platen, ink to printing the first color after bonding (omitted in), you can set sec

20、ond color, the color printing (including overprint) until the completion of requirements, remove the substrate for postprocessing (drying and fixation, pressing etc.). Put on a new substrate. The registration accuracy is improved by the tension of the whole screen screen, the tension of the net scre

21、en, the net frame rule and the screen pattern consistency of the same position.Rule of 1. net frameThe four rule on the side of the net frame is the positioning device in the screen printing, so the registration is still done by the rules. The rules of the screen frame should be unified and the erro

22、r is small. The rules and rules on the platen hole can not be too loose or too tight, too loose affect overprinter precision, tight unfavorable operation screen.2. screen makingAccording to the original design, the fabric should be overlapped with the color separation film to check whether the regis

23、tration accuracy meets the design requirements. After reaching the requirements, determine the cross, vertical two benchmark lines on each negative. Look for the base line of film on the production screen, make the film base line are connected with the screen coincide, so that the pattern can be mad

24、e in a unified position of each of the screen frame, in order to screen printing registration, which is the fabric printing registration key.Fabric printing pattern of the original mostly painted on tracing paper, directly as a film, so the drawings can determine the set of quasi reference line.3. o

25、verprinting orderFabric screen printing is both practical and artistic. It is of great significance to screen the silk screen well and satisfy the design requirements.According to the degree of difficulty of screen printing products color depth, color shading, pattern size, printing, special printin

26、g (ordinary printing in the same screen printing products, printing and printing etc.) the selection of printing sequence. The printing order is based on the quality of the final screen printing.Usually, the ordinary printing (screen printing dye or paint) and special printing (foam, luminous, pearl

27、 and other printing) in the same screen printing products, printing printing printing should be ordinary special printing.If the overprint colors, especially the overprint requirements, should be printed on a dark, light coloured after printing. If the printing and overprint exist at the same time (of different colors), after the first printing overprint. If the size of the pattern is very different, you can print small, big print later.The printing order should not be considered in one respect and should be taken into consideration in order to obtain the ideal silk screen for fabric.
