    Wedges for platemaking and chemical proof    

We are able to produce ancient contact control wedges.

They are produced by contact exposure of ultra fine-grain matrix onto UV daylight film. Individual elements (dots, lines) are prepared in 10times enlargement and then reduced by special microfilm technique.

Elements are therefore geometrically identical, with high sharpness of edges.

 

MHG

 precise offset test wedge for complete control of platemaking and chemical proof. Dot areas 0,5 to 99,5% (150 lpi screen), microlines 6 to 30 Ám, precise grey step wedge (densities 0,15 to 1,95, 0,15D progression).


 

MRG2

Economy offset test wedge for complete control of platemaking and chemical proof. Dot areas 1 to 99% (150 lpi screen), microlines 8 to 20 Ám, precise grey step wedge (densities 0,15 to 1,95, 0,15D progression).

Available also as MR2 without grey step wedge.


 

 

 

MRG1

The simplest offset test wedge for rough control of platemaking. Dot areas 1 to 99% (150 lpi screen), microlines 8 to 12 Ám, grey step wedge.

 

MRG3

Universal test wedge for copying

It is designed for film contacts, but applicable for plate making as well. Microlines 8 to 20 Ám, 6 dot areas 1 to 99%, grey step wedge. 


   

    Transparent grey scales for platemaking   

Densities of our grey step wedges are strictly controlled. 

Precise wedges reach the target density with accuracy ▒0,02D on all steps.

Precision of other scales is ▒0,05D.
