Numbering
I am so new to all this I might still have on diapers .. Been in the DIGITAL Print business for years. Went in with a offset business a few years back ( bad deal) partners just don’t work anyway … he was an awsome press man and did all the back work so I never learned how to number… the deal went south but I still have to number have bought 2 cheap count numbering machines and both have problems so I looked over and have this awsome old hedielburg sitting there that is dying to start numbering again…
can anyone give me instruction on where to even start .. I have read all the manuals and looked online here for weeks.
My issue is simple I think … My numbers are not crisp and clear I have the packing to the proper amount I think … and I adjust the pressure but then it is too deep turn back a little and they do not go throught the 2 part…
Please post pictures.
Are you using too much ink?
Did you use the packing gauge on your Heidelberg?
What kind of numbering machines are you using…is the plunger (the No. part) high or low?
What is the orientation of the numbering machines….vertical or horizontal?
Even though the issue may appear to be simple….it usually is more involved than it appears.
Feel free to contact me and I will be happy to help you trouble shoot.
If you are using the Count brand Bimatics, then be aware that these are easily damaged usually through crash imprinting, and that’s what you are describing, where too much impression is used and the shafts can be bent. Bimatics are no longer being imported from Italy, and if you sourced these from other than a dealer or Count, you probably have damaged machines. Careful makeready, and that’s not defined by more overall impression, can bring the numbers up. Otherwise, get some decent machines like Liebinger or Atlantic-Zeiser that are still made, and then learn how to take care of them.

spot on answer you dont crash with any box that has sink able zero,s if the zero can be sunk you have the wrong boxes you buy crash no boxes buillt for the task , leibinger being the best i have ever found , we have over 200 boxes here of various makes and styles many are victims of crash numbering by philistines of the worst order. I repair as i need to use them , I bought every spare part i have ever been offered for various makes so i dont struggle like many of you will but a bashed box will always produce dissappointing results however hard you try. As mentioned get low plunger boxes or the plunger will chew your rollers to bits and take time to make ready, avoid patching to the back of the boxes unless you use steel shimming or you will push the plungers out the back of the box over time ,rendering them beyond repair. soft inkers are most helpful so the inker doesnt jump the first digits of the line when numbering horizontally . The plungers will always dig in a bit but you can get around that with hard packing under the tympan where the No falls and soft where the digits fall.
Note the boxes for crash numbering are not gothic nor do they have serifs and in fact look like the numbers of the univers font.
