If you're looking to eliminate film from your darkroom workflow, improve screen accuracy, and reduce long-term material costs, the SAATI LTS E70B Laser Exposure Unit is the tool to get you there. This Laser to Screen (LTS) system is designed for small to mid-size screen printing shops ready to modernize screen creation and streamline production.
In this guide, we'll break down how the SAATI LTS E70B works, why it’s different from traditional exposure units, and how it helps your shop save time and money while delivering unmatched image quality.
Why Go Laser to Screen?
Traditional screen exposure involves multiple steps: film output, registration alignment, vacuum setup, and light exposure. Each step introduces opportunities for error, misregistration, or lost time. Laser to Screen (LTS) technology cuts through the clutter by imaging directly onto emulsion-coated screens, no film, no ink, no glass.
The SAATI LTS E70B makes it possible to create consistent, high-resolution screens with minimal manual labor and maximum precision.

Top Benefits of the SAATI LTS E70B
High-Resolution Laser Imaging
This unit comes packed with 64 precision lasers and selectable resolutions of 1270 or 2540 DPI. Whether you're producing bold text or smooth halftones, the detail is crisp and repeatable. That kind of resolution used to be limited to large-scale shops but the E70B brings it to small and mid-size operations.
No Films, No Problem
The LTS E70B works directly with 1-bit TIFF files, removing the need for consumables like film positives, ink, wax, or glass. You’ll save money and storage space, plus you'll never deal with clogged printers or warped films again.
Built-In Pneumatic Frame Clamping
The integrated clamping system works with standard registration setups like MHM and Tri-Loc. That means your screen stays locked in place during exposure, giving you dead-on accuracy across every print run.
Workflow That Works With You
This laser unit plays nicely with most RIP software and supports hot-folder automation. You can even save exposure settings by screen type and mesh count for repeat jobs or multiple press setups.
Low Maintenance, Low Overhead
Running on standard 110 V power and compressed air (90 psi at less than 1 CFM), the LTS E70B is easy to install and maintain. Its laser array is rated for over 10,000 hours, keeping long-term operating costs low.
Compact, Vertical Design
The E70B’s vertical layout makes it ideal for tight screen rooms. It supports screens up to 25 x 36 inches, with a maximum image area of 23 x 31 inches.
What Is LTS in Screen Printing?
LTS stands for Laser to Screen, a screen imaging technology that digitally exposes artwork directly onto emulsion-coated screens using laser beams. With an LTS exposure unit like the SAATI E70B, screen printers gain sharper detail, tighter registration, and faster turnaround while reducing long-term operating costs.
