CTP — Digital Exposure
Direct-to-plate imaging without film negatives
Direct Digital Exposure Technology
CTP (Computer-to-Plate) digital exposure technology completely eliminates the need for traditional film negatives, imaging plates directly by removing the LAMS (Laser Ablation Mask) layer with a high-precision laser. This technology delivers exceptional resolution ranging from 2,540 to 4,000+ DPI with HD screening technology that produces flat-top dots for the highest possible print quality.
At Unidots, we use the latest Esko CDI Crystal equipment or equivalent, ensuring precise control over every detail of the plate. This technology enables production of HD ultra-high-definition plates, with the ability to handle all LAMS plate types available in the market, achieving a minimum dot size of 10 microns.
Digital Exposure Process Stages
Digital File Preparation
Receiving and reviewing digital design files to ensure they meet required specifications, including color separation and halftone screen settings.
Laser LAMS Ablation
The high-precision laser removes the mask layer (LAMS) from the plate surface according to the digital design, creating an accurate image directly on the plate.
UV Exposure
Exposing the plate to ultraviolet light to photochemically harden the exposed areas, forming the final printing surface with extreme precision.
Processing
Processing the plate through washout, drying, and post-cure stages to remove uncured areas and prepare the plate for use on press.
Quality Inspection
Comprehensive inspection of the finished plate using precision measurement instruments to verify resolution, detail accuracy, and dimensional conformance to specifications.
