CTP-XT Processless Thermal CTP Plate
Brief Introducton
CTP-XT is a new green printing product suitable for thermal CTP platesetters. There is no need of any processing steps before mounting exposed plates on press. It can be put on press directly without processing. The plate ensures good performance, such as excellent dot reproduction, wide exposure latitude, good latent image and plate-making stability, and long run length.
Features
1. Negative non-ablation photosensitive system
2. Compatible with the dominant devices in the market
3. Can be printed directly on press without any processing steps after exposed by thermal CTP platesetter
4. Good dot reproduction, stable performance, wide processing latitude
5.Long stability of latent image, can be stored at least a week after plate-making

Attention
1. After imaging exposure, the longest time which plate can be placed for without affecting the printing quality is the latent image stabilization.
2. The paper number of start-up is the paper number at loss from the first paper to providing completely clean background.
3. Printing methods: firstly clean the ink on the rubber blanket with washing water, run water roller 30 to 60 seconds, and then close the ink roller to run for 20-40 seconds and finally start paper printing
Application
1. Suitable for sheet-fed offset press or high speed rotary offset press
2. Run length: 200,000 impressions
3. Suitable for different types of traditional inks and fountain solutions, including alcohol’s substitutes as fountain solutions
4. Unsuitable to improve run length by baking plates
