creasing matrix size for lettra 110#

Curious what scoring rule and creasing matrix sizes you use for scoring Crane Lettra 110#?

I have had issues with cracking when scoring this paper and have posted in a previous thread but I didn’t ask what creasing matrix dimensions others are using. I’m using a 2pt steel rule.

Fritz from NA Graphics is sending a few sizes for me to test but I thought I’d ask what others are doing.

I use a 2pt rule with NA graphics’s mauve matrix (**edit** I had originally written white, sorry…. I shouldn’t be allowed to post at 3:30am!). It works great every time. I’ve actually been using the 2pt rule in .895 depth (just under type-high). If you have set your press for deep impression, it saves adjusting the platen to avoid damaging it or bending the rule.

The NA Graphics website suggests using Mauve for creasing Lettra:

“…with a slightly wider channel than Yellow; Mauve, .020-.024”, recommended for Crane’s Letra.”

I recently ordered and used Mauve on a job and it seemed to work fine. I’d love to hear if anybody has had better results with a different size.

What about by hand? is there anything out there?

I am having troubles creasing lettea by hand as well, no matter how much and how hard I crease it with a bone folder, dampen it etc. People have said good things about the scor-it board, so I am going to go get one and try that. I will let you know how I do.

I’ve always had good luck scoring by hand with the back of a table knife onto a sheet of chipboard.


Without a channel matrix it helps to score WITH the grain.

Is there any real definitive answer on this (scoring 110# lettra)?

Mauve, white? NA Says mauve for 220# and white for 110#. What are others’ experiences?

You could try “slit scoring”….you use a cut rule and kiss the paper to create a score/kiss-cut that only cuts through part of the paper. Fold the paper so the slit score is on the outside of the paper. It leaves a nice clean edge. If you don’t have any cut rule you can do it by hand with a sharp exacto knife and a ruler. Next time you are in your local store look in the greeting card department and you might see some examples of this….although I’m not sure very many big box greeting card manufacturers use lettra for their cards.
If you are using matrix put a piece of scotch or clear box tape over the matrix. Add another layer if needed to get rid of the cracking. Or don’t use matrix, instead use 4-6 layers of masking tape covered with the scotch or box tape. Don’t use the cheap dollar store brand, spend the money on quality tape.
If all your other methods fail, deboss the score with a proper male female counter and die on a press that has heat set at app. 300 degrees F. Good luck!.

In the land before matrix counter score, I used to use duct tape. The key was the find a brand with a good body (not showing threads). This was used in combination with cutting rule (die-cutting pocket folders). It would usually take three layers to get good results—cutting out corners was required to prevent puckering and cracking.

My friend uses strapping/fiber tape for his scores. With all the digital printed paper he is getting into his shop it is the only thing he has found that works for him. You can find pictures here

So, you use a scoring rule and a thick pile of tape in the place of a matrix?
