Experience: getting started screen printing technology - screen printing, screen printing - screen printing industry, especially

1, Network box Generally have two kinds of wood frame and aluminum frame Wooden frame relatively cheap, suitable for hand Print , But recovery is rather poor, because the wooden frame pulled out of the net is easy to loose, reduce the net recovery of the price range for a few dollars, compared to wood frame aluminum frame has its effects reach high recovery , not mentioned here!

II Gauze There are many, such as nylon mesh, Polyester mesh, metal mesh yarn, with the applicability of cost considerations, the general use of nylon mesh, can also color differences, net yarn for dyeing, which it is relative to the four-color, because the dye can mesh moiré phenomenon, which is later to say, not say here, that I remember said mesh front mesh, I said "T" only a mesh model, mesh representations should be mesh / square meter, the general 77T = 180 projects 100T = 250 projects 120T = 300 projects head 165TT 140T = 400 and so on, and I do not remember, do not know , requested the master to correct the other mesh are 43T. 34T. There are other models ranging from!

3, Pop Netting manual, mechanical, pneumatic drawing in the net, for general printing plant, requirements are generally not too high in order to fully address the first two, the latter La Machine I have not used, only in books and seen! Netting, is to screen frame on the net machine's stand, then rub on the strong pull network Glue , Then the mesh on top, solid firm, and then pull all sides can be measured with a dynamometer is the same force on all sides, until a certain intensity, then to network box on top, then rub on the surface of glue so closely mesh with adhesive secret network box, and so it is dry, can be removed. There is the wooden frame, you can use to fight nail up on it, the principle is similar to other point of issue for a later date!

4, washing net Washing net washing generally use a dedicated network of chemicals, but a lot of trouble, until the time that oil contamination removal, has spent a lot of time, the average processing plant, about aging, not to wait, I am here to talk One had a very effective method is to use detergent, of course, to the kind of strong detergency is Tide, or other brand, which is up to you. Oh! Wetting stencils, the other is polished with a cotton cloth, so there is another advantage, that is conducive to the adhesion of photosensitive paste. Province, a polishing step. Remember to double-sided polishing, there is the positive, polished, the force must be light, to avoid the shedding mesh. Then put Dryer Drying, alternate.

5, the photosensitive paste 1 Before speaking, it is necessary to talk about the sensitive pulp, do not speak a photosensitive slurry preparation, or from the market to buy more assured, of course, domestic and imported, is used in my previous all imported goods, Italy photosensitive paste well, such as `net yarn, yarn over the net, Switzerland, Japan and Germany gauze, of course, this is my one-sided story, which depends on your own. Market requirements photosensitive paste their own call, you can powder with hot water first photosensitive humidity and after full mix thoroughly into the sensitive pulp and put a few hours later use. Large plant with automatic sizing machine, thickness is uniform, small plant sizing for yourself, who can plate to complete!

The photosensitive paste 2 Is posted capillary film is film diaphragm, which is relatively simple, the so-called contrast with the photosensitive paste, and indirectly, a direct method, (do not know see above) you just need to film film and humid affixed to the place you need, then sizing containers, gently pressing to make membrane embedded network yarn, drying the water, put up grill plate machine.

6, baking sheet; Baking sheet baking sheet in the machine to the temperature around 30 degrees generally warm air baking, if there are many sizing process, there will be many times baking, pay attention to is that some baking stencil To a dry, otherwise you must know the consequences. Mainly looking for the thickness of the substrate, and different substrates have different thickness, for PVC, such as thin film is usually a can, and for things like cloth and so must the thickness of the rough, or very easy to break.

7, published Noted that the integrity of the characters, and slick conditions, if any tooth profile and other reasons, the high accuracy, then have to re-dried version of it!

8, printing Not mentioned here!
