2+1 Label Flexographic Printing Machine

Flexo label printing machine CY series

High-speed. Fine , vivid color and exquisite printing quality.

Washing durable and colorfast.

Environment-friendly good at printing various kinds of label.

Application to: polyester label tape, nylon tape, cotton label tape, herringbone tape and roll paper.

Machine features:

Machinery in the process of operation ink will be evenly spread-out on the anilox-rollers, then transfers to the printing cylinder.

The flexo photopolymer plate will collect the ink and press directly on the surface of the material. Variable label length can be printed via changing different printing cylinder size.

Machine advantages:

1. Aluminum alloy panel

2. Japan bearing

3. Original imported silica gel heating plate

4. Korean carbon fiber heating device

5. Anilox rollers printing cylinder interchange

6.Varible frequency motor

7. Matching with parameters of UK Focus

1. Printing plate blank part of the roughened surface wear prone to failure
Over a long period, the roughened surface of the blank area may be worn away, resulting in:
(1) the water performance of the printing plate is reduced, you must increase the supply of Fountain Solution, to maintain ink balance.
(2) printing plate surface storage of water, adsorbed on the printing plate surface of less colloid, if printing short-term stop, do not rub glue is easy to get dirty, to the production of great inconvenience. Roughened surface wear more serious words. You must replace the printing plate.

2. Common Troubles and solutions in ink and wash printing
Problem 1: substrate bonding, rubbing dirty
Reasons for failure: 
(1) The ink does not dry; 
(2) rewinding tension is too large; 
(3)Storage of printed materials at room temperature is too high
Solutions: 
（1）Increase drying temperature; 
（2）Reduce rewinding tension; 
（3）Print the finished product in a cool place

Problem 2: The burnt version and the black version
FAILURE REASONS: 
1. The printing plate is too shallow; 
2. Printing pressure is too large; 
3. Too much ink; 
4. ink viscosity is too high; 
5. INK DRYING RATE IS TOO fast;
Solutions: 
1. Deepen Plate; 
2. Adjust Printing Pressure; 
3. Reduce Ink Supply; 
4. Reduce INK viscosity; 
5. Reduce the drying temperature

Problem 3: Poor color overlap
Reasons for failure: 
1. Multicolor overprint the color behind, before a color is not dry; 
2. After the color makes before a color stripping phenomenon; 
3. After the color overprint does not go up

Solutions: 
1. Increase the drying speed of the first color; 
2. Reduce the viscosity of the post-printing ink or Reduce Printing Pressure; 
3. Reduce the viscosity of the post-printing or improve its adhesion

Problem 4:Printing pinholes
Reasons for failure: 1. Ink Roller drying too fast, uneven ink transfer;
Solution: 1. SLOW DOWN THE DRYING RATE OF INK;

Problem 5. Too Light
Reasons for failure: 
1. Ink viscosity is too low; 
2. anilox Roller Line is too thin; 
3 anilox Roller Wear or not clean; 4. Inking is too small

Rule Out methods: 
1. Increase The viscosity of ink; 
2. Replace the Coarse Line of Roller; 
3. Replace with a new roller or roller for thorough cleaning; 
4. Reduce ink roller or knife pressure or appropriately increase the version of the roller pressure (gravure), speed up printing (flexography).

Problem 6: It’s too dark
Reasons for failure: 
1. Ink viscosity is too high; 
2. anilox roller is too thick; 
3. Ink Color Saturation is too high; 
4. Ink Volume is too large

Rule Out: 
1. Add diluent to reduce viscosity; 
2. Replace Fine Roller; 
3. Add desaturant to reduce color depth 
4. Increase ink roller or scraping knife pressure or appropriately reduce the pressure plate cylinder (gravure) 

Problem 7. blotchiness in print
Reasons: 
1. Plastic film uneven thickness; 
2. Ink is too thin; 
3. Ink viscosity; 
4. Printing plate ink is not uniform

Rule Out: 
1. Replace the thickness of the uniform film;
2. ADD NEW INK; 
3. Increase the stickiness of ink; 
4. Check the cause of uneven ink transmission from ink and for ink
