non bearer to bearer machines like Hamada, Gestetner....Adast...etc...

So, I would be grateful to you if any of you could tell me some rough
idea about that......if impossible just let me know at least about the
Heidelberg's Blanket to Plate strip width when properly set the bearer to bearer pressure according to the Heidelberg Manual......


Awaiting for you inputs.

Thanks

8to9 mm strip

3/16 of an inch should be fine. Don't over think it, Just make it even across the cylinder.

Hi,
I set ink strip between plate and blanket to 2mm however, non bearer to bearer machines(like our ab-dick360) are not very consistent about pressure so, depending on the results and/or needs, i set it up to 4mm(but this WILL cause premature plate wear, say 20 to 30k impression)
What roland 202 is suggesting(0,1mm pressure between) is correct, but it's just not about the width of an ink stripe, is about total pressure contact between two cylinders. The only way i know to measure this is with a bearer to bearer pressure machine and a op manual or a gauge. I guess you could try to measure that in your press but i feel it would not make any sense becuse of the lack of controlled pressure.

Hope that helps

Dear Tahir khan,tstruth ,m_alatorre, Marco Cobucci,

Thank you so much bothers for your valued responses.....
actually, i never thought this question would be answered....:-))))
anyway there are so many guys who love to be shared their knowledge with others..........

at the same time i must tell you that i had a dispute with roland 202 suisse
due to some language problem and misunderstanding about our communication....


But, Now i am so happy to tell you that he has become a good online friend
of mine........we are sharing our personal family photos also....
he's helping me every possible way of he can to over come some sort of problems...
see how wonderful this forum is.......

I love you.....i love you so much Colorprinting Forum.......Keep this up forever...


that's enough.......back to topic.......
after studying your responses i could come to a conclusion that
Blanket to Plate strip would be 3.5mm to 5.0mm is safe......

but dear Tahir khan you suggest 8-9mm.....can you please tell me to which machines
you suggested this much.......is it for Heidelberg machines....


Once again Thank you sooooooooo much friends......

demel

hi, 5mm is not safe. ok run only in severeral case.

Hi Marco Cobucci,


Thank you so much for your reply....
Yes you are correct......now i am having image doubling
problem when i set to 5mm....so i'll give it try for 4mm...

Dear Marco could you please tell me do i have to follow the same
value to blanket to impression......or should it be little higher value than blanket to plate.

awaiting for your reply...

Thanks

[QUOTE=demel;5551]Hi Marco Cobucci,

I tink the image doubling is coused by other trouble not the 5mm.


Dear Marco could you please tell me do i have to follow the same

i dont now how are the correct mm. but you know in the press job: 1time you go to 0mm, so go to print and increase the mm. to achieve the correct image you can get.

sorry if you dont andrstend wath i can say, but you are welcome.

Dear roland 202 suisse,

These are real people with real printing problems. If you do not posess the knowledge to respond to them in an intelligent manner, then you have no business responding! We sugest that you listen and learn instead.

Demel,

On bearer to bearer presses we allow no more than a .005 squeeze between the plate and blanket. On a press such as yours,which I asume is spring loaded, You should try to produce a nice even 1.5 mil. stripe. If your stripe is not even, then put on a new blanket and try it again. Once you have this set,leave it alone. You should never have to really adjust this. Perhaps you should have your mechanic come in and set it for you? After he has set it,never touch it.
