1. Exposing time
The exposing time under ***0W lodine gallium lamp at 1 meter is about *5S. If the power of the lamp and the distance to the plate are different, please expose the plate abiding the data in the following table.
2. Developing
Developer: Fuji DP*4 developer or our company’s ARFA*2 developer
Temperature: *5±1°C Time of Developing: *0+/**0s
The developer’s dilution ratio:
Automatic plate processor: 1:6
Manual plate processor: 1:*0
Notes: Our PS plates required weak alkalinity developing; the developer’s concentration, temperature and the developing time should be paid much attention, or it will decrease the run length and the printing efficiency. On the developer or developing powder which are produced by other companies, please use it under the condition they required to achieve our standard.
7 The reason of problems may happen and solutions
|
Problems |
Examine process |
Reasons |
Solutions |
|
Surface breezing |
Exposing handling |
Plates have been wrinkled. |
improve the way of handling the plate |
|
Exposure |
Light source is too closed to the plate. |
Adjust the distance between lamp and the plate longer than plate diagonal. |
|
|
There are dusts on the film and the glass on the exposing machine. |
Clean them with specialized cleanser. |
||
|
Exposure Non-homogeneous |
Exposure |
Light source is too closed to the plate. |
Adjust the distance between lamp and the plate longer than plate diagonal. |
|
Light source do not positive align to the plate. |
Adjust the light source positive toe the plate. |

|
Text Fragment |
Exposure |
Dust on the glass of the exposing machine. |
Clean them with specialized cleanser. |
|
Low run length |
Exposure |
Exposure degree haven’t achieved (Negative plate) |
Check the real exposure degree by step guide, increase the exposing time. |
|
developing |
overdeveloped |
Check the dilution rate, temperature of the developer, and the developing time |
|
|
Adjust the reel roll pressure |
The pressure between plate and rubber sheet is too high. |
Decrease the pressure , and check it scheduled |
|
|
The pressure between ink-roll and the plate is too high. |
Decrease the pressure, and check it scheduled |
||
|
Rubber sheet |
The elastane of the rubber sheet is weak |
Replace the rubber sheet |
|
|
Handling |
Overexposed(Positive plate) |
Check the real exposure degree by step guide, decrease the exposing time. |
|
|
Fountain solution |
The concentration of the solution is changed |
Using the supply point. |
|
|
Plate splitted |
Lock-up |
Plate is been distorted and splitted when locking up |
Be careful to lock up |
|
Handling |
Plate has been wrinkled |
Be careful to handle |
|
|
Ink shortage |
gumming |
Gum is too thick or not well distribute. |
Diluted the gum, and find a good way too make the layer well distributed. |
|
Baking |
Baking gum is too dense |
Well-distribute the baking gum on the surface |
|
|
Adjust the printing pressure |
The pressure of the plate cylinder—blanket cylinder and impression cylinder –blanket are low. |
Increase the pressure, and check it scheduled. |
|
|
The pressure of the plate cylinder—ink roll is low. |
Increase the contacted pressure, and check it scheduled. |
