EMULSION REMOVAL 101A

Part 5 in the  RhinoTech video series targets the tips and method on how to remove the stencil from the screen frame after printing is completed, so that you gain a new-looking screen frame in its place.

TOOLS for SUCCESSFUL EMULSION REMOVAL PROCESS

ERG8550L that is a ready-to-use Emulsion Remover. It rapidly removes emulsion and capillary film from screens, offers excellent freeze/thaw characteristics and is ideal for use in all climates.

RhinoCleanWashout Booth that is available in a variety of standard sizes. Its compact, space saving design and durable construction in Polypro continues to be the foremost choice for screen printers.

The RS1500APressure Washer that features a 26” hose, adjustable PSI from 250 – 1500 PSI, an adjustable nozzle, 110V and ground fault plug. It weighs just 60 lbs. in a very compact form and is a powerhouse of a system that just keeps on working year after year after year.

TECHNIQUE:

Apply ERG8550L to scrubber and scrub on both sides of screen.

As you notice in the video, once applied, the stencil begins to break down almost immediately.

After scrubbing, let the product sit for 1 – 2 minutes. Now, power wash (we use the RS1500A).

In a smooth motion, sweep pressure washer back and forth across the screen and experience the excitement of a new-looking screen frame coming into view!

Let screen dry. And, then you’re ready to reuse. It’s that simple.

Blocking out a Screen Frame 101A

Part 3 in our seBlocking out a screenries involves the steps to Blocking out a Screen Frame.

This how-to video follows previous demos: Coating Screens 101A and Exposing and Developing Screens 101A.

TOOLS OF THE TRADE from RhinoTech

The necessary tools include the screen frame that we previously exposed and developed, RB203 Thick Blockout that is water-soluble and a perfect choice to use on coarser mesh counts and a little squeegee. We also use the BL1620 Exposure Unit w/backlight.

NOTE: For finer mesh counts, the choice is RB202 that is a thinner product. For an absolutely permanent blockout, the choice is RB201.

STEPS TO BLOCKING OUT A SCREEN FRAME.

Puddle blockout in the corner of the frame. With the trusty yellow squeegee, spread blockout around the edge of the frame. This is important to ensure that all pinholes from dust are covered.

NOTE: RB203 is water-soluble making it easy to wash off the screen. And, the backlight on the Exposure System makes it easy to see where light is potentially seeping through, so you can cover those areas/spots with the Blockout.

Work carefully, though, to make sure that you don’t get any of the blockout on the image.

Let the screen dry.

DOUBLE SECURITY.

When the screen is dry, use regular packing tape to tape out around the inside edge of the backside (squeegee side) of the frame. This will ensure that when you print, no ink will get squished between the mesh and the frame.

And, that’s it!

RECAP:

RB203 – when you need a thick blockout for coarser mesh counts.

RB202 – when you need a thin blockout for finer mesh counts

RB201 – when you want a permanent blockout.
