When the emulsion is dry, place a positive print of your image on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WDGVKXF | | Best Sellers Rank | #646,704 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #758 in Screen Printing Accessories | | Brand | TECHTONGDA | | Brand Name | TECHTONGDA | | Color | Purple | | Customer Reviews | 3.9 out of 5 stars 10 Reviews | | Item Form | Bolt Of Fabric | | Manufacturer Part Number | 006854 | | Number of Items | 1 | | UPC | 748497501593 | | Weave Type | Plain | ## Product Details - **Brand:** TECHTONGDA - **Color:** Purple - **Item Form:** Bolt Of Fabric - **UPC:** 748497501593 - **Weave Type:** Plain ## Images ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 1](https://m.media-amazon.com/images/I/71P-IOpM5FL.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 2](https://m.media-amazon.com/images/I/71dcfnkvF7L.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 3](https://m.media-amazon.com/images/I/71imlj9sGhL.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 4](https://m.media-amazon.com/images/I/71zvxwAjQ5L.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 5](https://m.media-amazon.com/images/I/71qexfB9SqL.jpg) ## Questions & Answers **Q: My screens are 20x24 will this unit work?** A: The maximum external size of your screen frame must be within 25" x 21” **Q: This unit was damaged, do I have to pay for the return?
