CTP Printing Plate

Thermal CTP Plates InstructionPhoeneagle Thermal CTP plate(PGE) is designed to meet the needs of sheet-fed and we printing-consistency, cost-effective, easy to use and quality. This positive acting plate for 830nm CTP systems provides excellent imaging qualities and reliable printing behaviors. Consistency Computerized equipments on production lines monitor over 50 production parameters to ensure batch-to-batch consistency; Cost-effective Fast exposure speed without pre-heating. Long run-length; Easy-to-use Process under convenient daylight; Wide latitude and excellent reliability; Quality High resolution, rich tone, and quick ink-water balance. Specifications Run length is always dependent on exposure, processing and press conditions. Model PEG Application Commercial Printing Gauges 0.15-0.30mm Type Infrared sensitive, positive acting Substrate Electro-chemical grained, anodized and sealing treated Aluminium Main Features Easy-to-Use Able to work under white light; No need to pre-heat. High Resolution Special ingredients, together with the optimally distributed formula weight of binding polymers, in the coating of KTP offer fine dots with sharp edges and reproduce images with rich tone. Excellent Hydrophilicity Hydrophilic Treatment Post Anodizing Treatment(PAT Pic3) provides excellent Water retaining capability at the non-image area and prevents scumming. Multi-Grains Multi-Grains structure(Pic1 to Pic3) improves water Retaining capability and keeps ink-water balance optimally. Working Principle 1. Marco-molecules are formed by cross-linked micro-molecules during the oven drying procedure of plate production. Thermal sensitive coating with IR-Absorber; Hydrophilic layer formed by sealing treatment; Electrochemically grained and anodized Aluminium. 2. Infrared Laser exposures the non-image area. The IR-Absorber in the thermal sensitive coating converts light to heat and breaks the cross-linked structure. 3. The deformation of marco-molecules at the non-image area makes the coating alkaline soluble(Developer) 4. Image area remains insoluble to the developer. Guidelines Storage Store under Dry (relative humidity no more than 65%) and Cool(10-30) conditions. Keep away from chemicals. Shelf life: 18 months Exposure Apply on thermal CTP plate setters with following specifications: Exposure Energy: approx: 160mj/c Spectral Sensitivity: 800-850nm, peak sensitivity at 830nm Resolution: up to 1-99% 200lpi/20u FM Applicable platesetter: KODAK/SCREEN/CRON Develop Developer: Kodak Goldstar Premium plate developer 100% Develop temperature: 22-24 Develop time: 30-35 seconds. Deletion: KM-7(Gel), KM-1 & KM-2 (Pen) To remove the unwanted image on non-image area, you can use Image remover gel KM-7 or Deletion Pen KM-1,KM-2. Apply the image Remover on the dry plate for about 10 seconds and wipe off the residue. The residue on the plate will decrease the run-length. Using Phoeneagle Deletion Pen will minimize the side effects to the plates. Finishing: KG-2, KG-2S To increase the hydrophilicity of the non-image area and prevent the plate from fingerprint and other contamination, you should use gum solution (KG-2 or KG-2S, 8%-11% made by Gum Arabic) immediately after image removing. Wipe the gum solution on the developed plate and dry it. Gum solutions made by synthetic polymer are difficult to wash away before printing and result in poor roll-up performance. competitive price and good quality We are a professional manufacturer and exporter of ctp plate from Anhui China so that we offer you free samples to test the quality of our products.
