Product Description

Thermal CTP Plates Instruction

Phoeneagle 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 /square centimeters

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: 23-24

Develop time: 40 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.

 

Baking: KB-3

Remove unwanted image from plate with Deletion Pen, wipe the plate with bake solution(KB-3) and heat at 220for minutes. Before printing, treat the baked plate with developer for 30 seconds, wash with water thoroughly and then gumming.

specifications︰Based on the conventional positive PS plate which use specialized aluminum plate as its substrate, ink jet CTP plate is coated with ink receiving layer. After the documents been processed by computer and then printed with ink, the plate are to be made by exposing above the glass of vacuum printer(no need vacuum pumping), and then washing, developing or by constant exposure and wash and then automatically developing.
Ink jet CTP plate does not use films,and are mainly applied in printing of text and low & medium color printing (4 colors).

The applicable ink jet system: EPSON, ROLAND, MIMAKI, MUTON and other micro piezoelectric systems.
Advantages︰The Using Direction of Ink Jet CTP Plate

Ink jet CTP printing plate (positive) pushed out by our company for printing industry is dedicated for realizing computer-to-plate making on ink jet platesetter.

Positive Ink Jet CTP Plate:
Based on the conventional positive PS plate which use specialized aluminum plate as its substrate, ink jet CTP plate is coated with ink receiving layer. After the documents been processed by computer and then printed with ink, the plate are to be made by exposing above the glass of vacuum printer(no need vacuum pumping), and then washing, developing or by constant exposure and wash and then automatically developing.
Ink jet CTP plate does not use films,and are mainly applied in printing of text and low & medium color printing (4 colors).

The applicable ink jet system: EPSON, ROLAND, MIMAKI, MUTON and other micro piezoelectric systems.

Using direction:
1. Open the package and then fetch out the plate with your two hands grabbing the two sides of the plate, avoiding to touching the plate face.
2. In case the wrong printing, you must insert the plate to the right place of the ink jet platesetter. The printing ink should be fast-drying pigment ink and dye ink.
3. Exposure: expose immediately after the plate is printed, or else may be distortion of the dot and line. If the relative humidity is relatively large, the printing plate can not be timely sulfate, this does not affect exposure, but before the exposure process is completed, any object touching the graphic part of the layout should be prohibited to prevent the text loss, then lead expose failed.Expose the printed plate above the glass of the printer, contral the expose time according to the form below:. (details depends on the degree of aging of the exposure machine, and during expose, couldnot get bubble on the plate, or else expose fail):
1kw 2kw 3kw 4kw
0.6M 40seconds 20seconds
1.0M 45seconds 25seconds 15seconds
1.2M 50seconds 30seconds 20seconds 10seconds
1.3M 55seconds 35seconds 25seconds 15seconds

4. Wash :Wash off the printing layer of the printed plate immediately, with the running water under the normal temperature (temperature no lower than 25℃ ,using water of 40℃ will be better) and then wipe with the sponge which is special for printing plate, and then flush the front and back sides of the plates.
5. Develop: The same operation with conventional positive PS plate. (The developer concentration should be 1:4, it’s up to the actual practice). Please do not touch the image area after developing and make sure to wash out the plate,and no residue of the developer.
6. You can move to printing after the above process.

Storage condition and using environment:
1. Storage condition: (better to have dehumidifier or air conditioner)
   - This printing plate should be stored in dry warehouse with dehumidifier, avoiding being damp.
   - Storage temperature: ≤30℃, humidity: ≤60%
