STEP 3: MAKING A SCREEN
once you have printed on the films, it is time to make the screen door. A sieve printing frame consists of a wood or aluminum frame stretched with polyester engagement on it. The enmesh holds the effigy onto the screen and lets ink pass through when you press it with a squeegee. You will need to coat the engagement with emulsion in holy order to expose the design onto the screen door. Before you coat the interlock, it needs to be cleaned with a limited screen printing degreaser to ensure any debris, lint, or particles is washed off so no bulge or pinholes appear in your emulsion .
emulsion is idle sensitive, so coating the screen is typically done in a benighted board that has especial light-safe yellow bulb in it .
Applying the emulsion onto your screen requires the use of a outdo coater. You should select your soap coater size based on the size of your blind. A 4″ dispute between the scoop coater size and the outside dimensions of your riddle is recommended. This allows for a small space of open enmesh on all sides of your scoop coater to make coating easy while giving you the largest comfortable area for print .

Most scoop coaters have two edges. One is more attack, and can be used to create a slenderly thicker level of emulsion for more ink deposit onto your dress when print. Thicker emulsion layers are useful when printing on sweatshirts and for other high-density applications. The early border of the scoop coater is called the sharp boundary, and will allow you to coat your screen with a thin level of emulsion. Thinner layers are great for printing water-based and free inks, or if you want a softer hand on your dress .
To coat your screen with liquid emulsion, first make indisputable that your emulsion is appropriately mix and that you are in a light-safe area. Pour a minor sum of emulsion into your exclusive coater, enough to fill the stallion bottom of the scoop coater evenly, from one side of the end capital to the early. Hold the screen vertically with your non-dominant bridge player, shirt side out .
If you do not have a darkroom, there ‘s another manner to make a screen. Using estrus transfer vinyl ( HTV ), cut and weed out the design. Place the vinyl on a screen and you ‘re ready to print. A vinyl stencil works well, but for shorter runs. It ‘s best to use plastisol ink when using a DIY screen because the water in water-based inks will break down the stencil agile .

STEP 4: EXPOSING A SCREEN
After the sieve is coated and dried, align your film convinced onto the filmdom and expose it with a riddle printing exposure unit or an exposure light bulb for an allotted sum of time. The screen hardens to light, but the film positive or black area of the film blocks light from reaching the emulsion. This leaves the area of emulsion unexposed or soft .
Finding the right exposure time is a unmanageable undertaking. many factors like type of emulsion, type of exposure whole, enmesh count, mesh color, humidity levels, and more can affect how long a screen needs to be exposed. You will have to perform many tests before going into production. The best matter you can do is invest in a 21-Step exposure Calculator. The calculator will tell you whether the filmdom is over-cured, under-cured, or perfect. Learn how to use it .
After the riddle is exposed, plainly rinse it with water. The soft function of the emulsion that was not exposed rinses out, leaving areas of the engage open that reflects your design .

Of course, if you have more color arms, you have the ability to print more colors at one clock. Likewise, if you have a higher measure of impression stations, you can print faster .

If you are printing a multiple color occupation, you ’ ll want to register the colors together so that they pipeline up correctly when you print all of the colors onto a shirt.

Before locking the print head into set above your shirt, make surely to flood the screen with ink. Once the print head is locked down, push or pull the blind printing ink across the shield to deposit the ink onto the shirt. You may need more than one round of this depending on how a lot ink was deposited. If you are printing multiple colors, follow these steps with your early screens .

This gives you the ability to print another color on top of your first level. Learn more about printing an underbase .

You besides need to cure your shirt after you are wholly done printing it. You can cure a shirt with a conveyer dry, a flash dry, or a heat imperativeness. The temperature at which the ink cure varies. Read the instructions on the ink container to learn the proper cure temperature. Water-based ink like Green Galaxy will cure between 300°F-320°F. Plastisol inks like Wilflex Epic Spot Process cure at 320°F. Low-cure plastisol inks like FN-INK™ cures at 260°F.

Since plastisol ink doesn ’ t dry out, it ’ south easily to clean. Lay your shield compressed and spray it with either an Ink Degrader or on-press slipstream and rub with a tabloid. Once the chemical is fully absorbed by the tabloid, repeat the process until the screen is in full clean .

Scrub in a round gesticulate on the movement and back of the screen until you start to see it soften. Let the chemical seep into the screen for 30 seconds. Please, do not leave the emulsion remover dry in the screen. If the chemical dries, the screen is no longer useable. After the time has passed, wash out the chemical and emulsion. Follow up with a degreaser and/or a dehazer. Store the sieve in a dust-free area to let it dry so it ‘ll be ready to be used again .
