Ulano qtx emulsion exposure times. More exposure will ...
Ulano qtx emulsion exposure times. More exposure will make the stencil more durable (harder), but light scatter in the mesh and diffused light from a longer exposure, can under cut the positive, and choke the final image size. I am a first time DIY screen printer (experienced with professional equipment lol) and doing a stencil with Ulano QTX emulsion, 4 9-watt LED UV lights (400nm), 5 inches from the lights, with the ink side facing the lights since I was doing it on the ground and using the baby oil and computer paper.

This might be one of the most common questions we see here in r/SCREENPRINTING. be reclaimed easily. I'm using Ulano QTX emulsion and a Ranar CBX 2024 exposure unit. Ulano QTX is an emulsion that is ready-to-use since it does not require mixing like the Ulano 925 WR. QTX is a ready-to-use, ultra-fast-exposing SBQ-photopolymer direct emulsion formulated for imprinted sportswear printing. The high®result solids content in superior of QTX coating properties, better drying. Ulano QTX Emulsion's high solids content provides superior coating properties, better bridging of coarse mesh, and fast-drying capabilities. I expose SAATI HU42 emulsion on a 156-158 mesh screen for about 13 minutes for best results. Do not subject to strong solvents during printing or washup. The high solids content of QTX results in superior coating properties, better mesh bridging on coarse fabrics, and fast drying. Using this chart from Ulano to calculate exposure times, I've conducted many step wedge tests. The black is very opaque. Ulano QX-1 Emulsion is presensitized and must be handled in yellow safe light conditions before exposure. Normally I can expose a screen in 45 seconds but it’s taking way longer with this new brand. Page 1 of 6 MSDS for #43315 - ULANO QTX EMULSION 43315-1007 George Legh-Page from The Ulano Corporation took some time while at Lawson to demonstrate the Ulano Exposure Calculator.

It is ultra-fast exposing SBQ photopolymer direct emulsion formulated for textile printing. Here is the deal - I recently switched from diazo emulsion to pre-sensitized Ulano QTX emulsion and am finding my old burn times no longer apply. This emulsions is super sensitized; my standard exposure for a 160 mesh screen is now down to 2 minutes, even less for higher mesh Ulano QTX Screen Printing Emulsion is a ready-to-use, ultrafast-exposing SBQ photopolymer direct emulsion formulated for imprinted sportswear applications. Expose with blue actinic light at a wave length of 320-380 nm. I accidentally bought a different brand of emulsion and need help figuring out the exposure time. ®is QTX resistant to plastisol and many water-based inks. For instructions, refer to the manufacturers' manuals or contact your distributor or our technical department. We fixed our problem by letting the emulsion on our screens dry for a full 48 hours before exposure, and by fixing the vacuum leaks on our exposure unit. QTX's high solids content provides superior coating properties, better bridging of coarse mesh, and fast drying. Find your correct exposure time each. QTX's high solids content (46%) provides superior coating properties, better bridging of coarse mesh, and fast drying. This emulsions is super sensitized; my standard exposure for a 160 mesh screen is now down to 2 minutes, even less for higher mesh Thanks for your submission to to r/SCREENPRINTING. Ulano QTX Emulsion is presensitized and must be handled in yellow safe light conditions before exposure. (10 – 15 cm. If you have, can you tell me how the quality is in relation to the edge sharpness and overall detail for small letters etc. QTX | 46% solids ultra fast plastisol emulsion - best for low UV energy lamps QX-1 | Pre-Sensitized Dual-Cure Hybrid Emulsion - Excellent humidity resistance, but slower than SBQ sensitized emulsions. I am wondering if anyone has used Ulano QTX Pre-Sensitized Emulsion for screen printing. It looks like the emulsion is soft, and I bet it’s sticky to the touch. Anyone know the correct exposure time with this unit would be? Thank you! Washout: After exposure, wet both sides of the screen with a from the printing side until the image areas are completely (scum) that might block the image area, rinse the screen Stencil removal: Use mineral spirits, or the least powerful ink Strong solventstencils can fuse to QTX ULANO the Screen fabric.

It's less expensive than QTX, but faster than diazo sensitized industry standards like Ulano 925. First test I did was 120 seconds, then 180 I have an 80W Led exposure unit. It appears you may be looking for information on exposure or burning screens. This emulsions is super sensitized; my standard exposure for a 160 mesh screen is now down to 2 minutes, even less for higher mesh The minimum exposure to cross link emulsion so water won't dissolve it and it holds in the mesh, is a Solid Step 7.

It's the diazo sensitizer that brings water resistance to most dual-cures, but at the price of longer cure times, so you have to decide what's important. Thanks, Rick. Due to the large number of machine types, it is essential to determine the exposure time in own trials. I haven't tried the Ulano QTX yet though. For plant-light, filtered black light, and "daylight" fluorescent tubes, use at least double the exposure time. 5-3 minutes with either Ryonets HD or the S. ) exposure distance.
