It seems that one of the most common problems new screen printer is printing with white ink. I have a lot of questions, to hear: Why do all my other colors and white fine print is so difficult? Why is it that my white ink is so thick? Because a smooth, white ink? It 's always seem to have rough texture. Can I do something to thin my white ink to print simply can? Even comments like: "Our white ink is bad, comes after a few washes.""There's something wrong with my key, press right if you are printing on white shirts, but when I click on the dark shirt, white ink for printing very confused."
Unfortunately, the answers to these quarries are usually in the printer itself. No, the white ink is not crowded, your printer will probably work well, and should not be necessary to dilute the ink. Yes, you probably need to change some variables and methods during the printing process. The truth of the mother is, the answer is inQuestion all the time.
So why the press working process screen and a little 'and then once you start printing with white ink, smash, a roadblock. The truth is that you may have done things wrong all the time, which did not show up is not easy. And 'such as swimming, surely, you can dog paddle and flounder around the pool all day. However, when it comes to swim long distances without the proper techniques that are working two and half year.
Print on lightThe clothing is much easier than printing on dark garments white. On a lighter piece of clothing, not so much ink is needed to achieve good coverage. Many times working with thinner inks. Viscosity of the ink varies, depending on the amount of pigment has in it. For example, a black ink is almost always going to be printed on lighter colors, the pigments for black to show much less necessary to cover the white pigment of a dark suit required. So, you're black inkto handle a lot thinner and lighter. Ask any technique incorrectly when printing black ink on white shirt, and there is still a good chance that your final print will be pretty good. Since the ink is thinner, so that it passes through the mesh much easier with less force, and clears the screen better. (For the reader with the concept of 'clearing the screen ", this defines the point at which all the ink on the screen cleared and transferred to network properly with the T-shirt.)
Sobeginning of the creation of a screen printing job that requires black ink on white shirt, you can use the wrong network screen, have no contact and can be printed with the squeegee technique completely wrong and still get an "OK" looking final print. However, if the same techniques have not attempted to correct printing with white ink, uh oh, game over! The problem is that many printers are starting to learn for themselves in this way and completely wrong. In fact, this is how I learned. It is not the end ofBut the world!
The first thing to understand, and cope with going is the fact that the white ink, is likely to be the largest ink you've ever used. To achieve this, a bright picture white on black, t-shirts, the ink is too opaque, which means thicker. Surely you can find a thin white ink, or trying to reduce the thickness, but to achieve victory on purpose and you will end up printing twice as much, to search for, and the same result. On the other hand, if you learnTo print correctly, so the pressure is white like a walk in the park
In recent years, each paint manufacturer in the country in search of "better" white ink on the market. Yes, they have come a long way. In fact, twenty or thirty years, white on black looked more like a light brown or gray to white. Now available in colors like white or Phoenix White Triangle Coatings, it is possible to obtain maximum coverage with minimum steps. However, white inkwith pigment that it will always mean high viscosity, were loaded.
So what's the catch? How can you print white ink as the
Professionals.? The answer is usually in a few simple changes to its structure and
Technology. Apply these changes and really not that hard.
Before examining the techniques, we first discuss a little 'pre-press and setup.
For a correct setting of a job with white ink, you must first
to understand a little 'selectionthe mesh size right. Since white is
more often, you want to print from the lowest appropriate mesh size, which is
and printing. If you try to print white through an upper screen, which is
much smaller holes in it to his will it much more difficult to push the ink through the screen. It 'also no longer allow the ink through the mesh of the screen would be less.
Typically, you want to print with mesh sizes of 110 to 156 white Granted sometimesImage requires a high number of points. For example, through tone or a fine line drawing can not keep a lower screen, you must use the high power and apply more to get a bright white. In most cases, however, you should lower the top, so that more ink is deposited the shirt.
The second part of the device is to make sure that your monitor is set correctly on the press. They want to be sure you have a contact right off of about 1/8-1/16Inches. Since white is a little 'thicker, it is advisable to go a bit' larger than normal contact, perhaps an inch 08:01. Outside contact is the height between the network and the substrate on which is printed.
Proper contact also allows the ink from the mesh easily removed by releasing the active network immediately after the stroke of the press, leaving all the ink evenly on the shirt. One thing you will want to make sure you apply when printing with white inka contact card off. This is a small piece of cloth (for example, a penny, cardboard, paper, a piece of plastic) which is the height from the contact. This register is at the end of the screen frame where it meets the top of the neck roll and place the T-shirt. Using a contact form will ensure that your contact will remain through the entire stroke of the press.
The card contains the end of the screen until you press down while the fabric during the race. Non-contactCard, you may find it harder to remove the network, because the screen will remain connected against the T-shirt with ink pot.
If no contact can cause some problems right off. If the contact is too low, then it will not be able to clear the screen properly. You should pass the mesh T-shirt and be able to see the ink and the shirt a free network. If your ink remains in the network and the network sticksthe shirt is, if you pull out the ink screen looks very rough and pull out the parts of T-shirts. If you are with this problem, you may need to increase the contact a little '. Moreover, this problem could come from the actual print process, which will be discussed later.
At the other end of the spectrum when it is in contact with high and you have to press too hard with the spatula to remove all the ink you get down on your t-shirt. I've been away from shopsCustomers who have literally almost half of the contact customs. If the contact is too high, it will be difficult to transfer the ink on the shirt, but it's a good chance that the screen will not be in the same place every time. This may flash an image blurry or duplicate images a. A contact is extremely important to correct street for a good image for research and printing easy.
Next we look at the technology. Most of the art in screenThe printing process involves printing the race. These include the angle of the blade, pressure, speed and let go. The default printer is a new trend literally to destroy the ink through the screen of the squeegee on the screen with a very shallow angle.
With the use of thin inks, this might work because impropertechnique ink through the screen easily. However, when you look with white, you not only have difficulties when the ink through the screen, but also veryblurred images because the shirt pulling so hard. The doctor should actually on an angle of 80-85 degrees to be facing. You should also focus the pressure above and below the pressure and not to train the squeegee against the mesh.
.
Many new printers are available again in the press that you really need to focus not on the state of press back and the press. When the pressure down carefully, then simply move the blade on the back of the print. Withthe correct angle of the blade, all the ink through the screen and push right of your screen. In fact, it should be possible to design and run your finger over the ink was printed after her as they appear on the finger.
Let us now speak of the speed of your printer. If we want to instruct the printer to use the correct blade angle and pressure, the first impulse is that they have to move the blade on the speed of a turtle. If the speed is too slow, will not be able to properlyIssue and the screen. After shaking a pressure, a lot of beginners to sit and look at their prone press, then slowly pull on the jersey does not allow the blade to bounce back to let the ink still glued to the screen. After a faster pace, it's almost have to bounce on the screen a pop just to protect the network can be strong even pressure on the T-shirt to get. This will be achieved with a simple flick of the wrist, the same film would you do, be sure to collect allThe ink on the squeegee. They can create and publish only in this pop-up and the screen, the film must be made a little 'faster.
Finally, when it flashes between the past, you must wait for some cool T-shirt ', up to print again. This is much easier to get more of a press station, because they can cool the pallet. Print a station may have to wait a few minutes and waving his hand across the range to cool.
When the ink is too hot outsidetheprevious Flash, you may have trouble clearing the screen, because the ink stick, rather than the output of the network. It could also lead to cure the ink in the network. Since white ink is thicker and contains many layers you apply, you must ensure proper care.
White ink tends to reflect heat instead of absorbing it into This means that the ink and the print area from top to bottom must be treated to 320 degrees for about 45 seconds. Obviously the best way toI want to know is healing in a conveyor belt equipped, if you use a flash dryer, you are sure that the whole structure receives the same amount of heat.
One of the best ways to ensure proper care is to test the path. Because your white image is a bit 'thicker, this test is easy to read results. After the T-shirt is healed, just take a small sample of your design and extend slightly between your fingers. If the drawing together like sticks of plastic and extends wellthen it healed and you can continue with the cooking conditions. However, if the ink cracks or breaks, this means that the basis for the ink is cured properly and is yourcuring need to increase the time for the T-shirt.
Following these steps and techniques you should find a white ink a little 'easier. Of course, because there are so many variables involved in screen printing, you may need a little 'work on it and change something. But after a couple of times the pressure of the rightTo begin to see better results and fewer problems.
