LED Exposure Unit IKONART compatible

£75.00

Description

An LED exposure unit uses direct and uniform light at full power that makes an ultra-fast exposure.

Around 50% faster than metal halide exposure units.

Not only efficient but also long-lasting. LEDs can last around 100,000 hours

The bright LED lights send UV rays that optimize for the exposure of screen printing emulsions.

To match the highest accuracy and production speed, it has 100 watts LED light with reflectors.

That creates an intense direct exposure at 65 LPI halftones in 120t mesh.

The exposure unit has an overall dimension of 5.5″(W) x 9.5″ (L) x 12″ (H), covering a Max Exposure Area of A3 sunlight stencil.

Sunlight stencils Exposure unit for Screen Printing is designed for conventional or direct-to-screen exposures.

It saves space and energy costs. Unlike metal-halide bulbs, LEDs do not waste power and last longer.

Complete light fixture to power LED.
In a light safe environment center UV LED Exposure unit directly above the middle of the screen at a height of 12-15 inches. Note: The higher your LED is, the longer your exposure time, and the more coverage to the screen.
Place opaque black transparency reverse onto shirt side of screen and tape to screen. If your transparency is not opaque your screen will not expose as well.
You can add a piece of thin clear glass on top of your screen to increase the positive pressure during exposure. This is optional but will increase the detail gained during exposure.
Expose for 4 minutes in a light safe environment. Note: Ensure your screen is bone dry before exposing. The more emulsion your screen has, the longer your exposure times will be. Increase exposure for lower mesh counts.
Washout your screen out with high pressure water in a safe environment.
Blot the image with newspaper or clean absorbent, then dry.

If your image does not expose or washout properly. First make sure you are in a light safe environment. Ensure your screen is coated with a thin coat of emulsion and allowed to dry so it is smooth to the touch. If your emulsion is tacky you need to either coat it with less emulsion or dry it for a longer period of time. You can use a clean fan or dehumidifier to speed up the drying process. Ensure your film positive is dark and opaque. Ensure your screen has positive contact between the film positive and the screen mesh. Add a sheet of glass or foam under the screen to increase positive contact.
If your screen exposes but is slimy, increase exposure time by 1 minute and try again.
If you can’t wash out the image then decrease the time by 1 minutes until the image appears

Ideal for the novice printer as this sheet is more forgiving when exposing, 3 mins under led uv exposure unit.
