Laser to screen printing technology is designed for small to mid-size screen printing shops ready to modernize screen creation and streamline daily production. If you want to eliminate film from your pre-production process, increase screen accuracy, and drop your long-term material costs, this system is the ideal tool for your shop. The SAATI LTS E70B Laser Exposure Unit provides a massive leap forward for standard darkrooms.
In this guide, we break down how the SAATI LTS E70B works, why it changes the game compared to traditional exposure units, and how it helps your shop save time and money while delivering unmatched image quality. Transitioning to a laser to screen printing workflow means you can say goodbye to the friction of traditional film positives.
What Is Laser to Screen Printing?
Laser to screen printing, often called LTS or computer to screen (CTS), is an imaging technology that digitally exposes artwork directly onto emulsion coated screens using high powered laser beams. With a dedicated laser to screen printing exposure unit like the SAATI E70B, screen printers gain sharper detail, tighter registration, and faster turnaround times while reducing daily operating costs.
By bypassing the film generation phase entirely, your darkroom becomes cleaner and more efficient. The laser targets the emulsion with extreme precision, curing the exposed areas instantly. This method removes the variables that often cause breakdown during traditional exposure cycles. You no longer have to worry about vacuum blankets losing suction, glass cleaning maintenance, or dust getting trapped between the film and the glass.
Why Shift to Laser to Screen Printing?
Traditional screen exposure involves multiple steps like film output, manual registration alignment, vacuum setup, and light exposure. Each step introduces opportunities for human error, misregistration, or lost production time. Modern laser to screen printing technology cuts through the clutter by imaging directly onto emulsion coated screens. This means running your darkroom entirely without film positives, costly printer inks, or high-maintenance glass exposure tops.
The SAATI LTS E70B makes it possible to create consistent, high resolution screens with minimal manual labor. When your team does not have to worry about static electricity, dust on the glass, or vacuum seal failures, they can focus on keeping the presses moving. This direct digital workflow ensures that the image on your computer screen matches the image on your mesh exactly.

Top Benefits of the SAATI LTS E70B
High Resolution Laser Imaging
This unit comes packed with a planar array of 64 precision lasers and selectable resolutions of 1270 or 2540 DPI. You get crisp, repeatable detail on bold text blocks and smooth halftone dots alike. High end laser to screen printing resolution used to be limited to large scale, industrial shops. The E70B brings this advanced capability directly to growing small and mid-size operations.
Advanced imaging means you can confidently accept complex artwork files from clients. You will know your darkroom can handle fine lines and detailed halftones without breaking a sweat or losing image fidelity on the mesh. Holding a five percent dot on a high mesh count screen becomes standard practice rather than a stressful gamble.
No Films No Problem
The LTS E70B works directly with 1-bit TIFF files, removing the need for daily consumables like film positives, ink, wax, or replacement glass. Adopting laser to screen printing helps you save money and physical storage space. You will also never deal with clogged film printers or warped films again.
Think about the time spent managing film inventory, troubleshooting wide format inkjet printers, and archiving old films. Eliminating those steps lightens your overhead and cleans up your shop footprint immediately. The reduction in material waste alone provides a clear path to a healthier bottom line for your business.
Built-In Pneumatic Frame Clamping
The integrated pneumatic clamping system works seamlessly with standard pre-registration setups like MHM and Tri-Loc. Your screen frame stays locked perfectly in place during the exposure process, giving you dead on accuracy across every single print run. This precise positioning is a core advantage of upgrading to laser to screen printing equipment.
When your screens are exposed in exact registration, setup times on press drop drastically. Your press operators can lock the screens into the press heads and start printing with minimal micro registration adjustments. This bridges the gap between your darkroom and your press room, maximizing your daily print capacity.
Workflow Automation That Grows With Your Shop
This laser unit integrates smoothly with most major RIP software programs and supports hot folder automation. You can save your specific exposure settings by screen type, emulsion choice, and mesh count. This is ideal for quick recall on repeat jobs or when managing multiple press setups in a busy shop environment.
Consistency is the foundation of a profitable shop. By standardizing your laser to screen printing parameters, you remove the guesswork from your darkroom technician's daily routine, ensuring identical results on every shift. Whether you are burning a 110 mesh for athletic inks or a 305 mesh for water based simulated process, the machine executes the job perfectly.
Low Maintenance and Low Overhead
Running on standard 110V power for US shops and requiring compressed air for the pneumatic clamps (90 PSI at less than 1 CFM), the LTS E70B is simple to install and maintain. Its durable laser array is rated for over 10,000 hours of use, keeping your long term operating costs remarkably low. This makes the transition to a digital workflow highly accessible for shops with standard utilities.
Traditional metal halide bulbs degrade over time, requiring constant exposure calculator tests and frequent, expensive bulb replacements. This advanced laser system provides stable, uniform light output from hour one to hour 10,000. You get predictable exposure times month after month without constant recalibration.
Compact Vertical Space Saving Design
The glass-free vertical layout of the E70B makes it ideal for tight, compact screen rooms. It supports standard screen frames up to 25 x 36 inches (640 x 920 mm), with a maximum active image area of 23.6 x 31.4 inches (600 x 800 mm). You get large format production capacity without sacrificing valuable floor space in your pre-press area.
When planning your darkroom layout, note that the physical machine dimensions are 81.5 x 28 x 74 inches. For efficient workflow and routine loading, remember to allow an additional 24 inches of clearance on the right side and 8 inches in front for the screen chamber door to fully swing open. Keeping your space organized around these specifications means less operator fatigue and better traffic flow.
