The LDS-506 Double Sided Laser Minilab Printing System is an upgraded high-speed, high-precision integrated double-sided silver halide printing device, optimized for large-scale, high-standard album mass production. Upgraded from traditional double-sided minilabs, it adopts dual-channel synchronous laser exposure technology to realize one-pass double-sided photo forming with higher precision and faster output speed. Equipped with intelligent constant-color calibration system, it maintains zero color difference on double sides and stable batch consistency. Widely compatible with RA-4 silver halide paper, ultra-thin album paper and special photo paper, it is the preferred professional equipment for high-end album factories and large commercial photo labs.
