Accordion Folds

Part of Metal Type’s Printing Advice section, here Phil discusses creating accordion folds.

If this was just an ordinary job on light weight card stock of about 9 thou; I would just comp up a form of plain old type high scoring rules and go with that.  Take the ink rollers out and run the stock through with enough impression so that the card stock folds easily.

I have often used hairline brass rule for this kind of job and scored all the scores or folds from one side.

But it all depends; for example, how thick the card stock is.  If the card stock is 12 thou or thicker, then this scoring with brass rule from one side only, will not work.  The results will be poor and there is a lot of danger that the stock will crack instead of folding like it should.

Printing Paper Bags

Part of Metal Type’s Printing advice section, here Phil discusses printing paper bags.

There has been some preliminary discussion about printing paper bags of late.  Questions about soft or hard packing and what kind of plates to use, and so forth.

Here is what I ended up doing after (in some cases) years of trial and error.

I used soft polymer plates; but with this kind of plate, I had to use a very  minimal roller pressure or roller contact with the form.  I found that too heavy a roller pressure caused very rapid wear on the plate.   And I had to ask the plate maker to etch out the plate as deeply as he could.

For the most part, no makeready was required on the work that I was doing.  Just put the job on the press and in this case I used Heidelberg platens, and set the  rollers to give barely a sixteenth inch touch and run the job. Read the Full Article . . .
