Deeper Impression

I ran my first few jobs yesterday and everything went well. The image looks crisp, I wish the impression was more evident. Any tips on how I might achieve this?

Packing on Press

I’m printing on a 10 X 15 Challenge Gordon.
I’m using 140lb cover stock.
There is a good amount of packing on the press some cover stock, some lighter weight paper. The throw off lever is broken, cracked down at the base of the machine. I think it may have broke in the off position, which would be a good reason why it needs so much packing.

Are you saying your press is always on impression?

I think he’s saying it’s always OFF impression, which- if that is true- is a terrible way to be running the press if you ask me.

You have to sometimes ‘work with what you’ve got’ but that is not a reliable way to do quality work if I take your description to mean your throw off lever is stuck so that the press is never in “print” always “tripped”.

fix your press
then work on print quality

You should be able to set the press to impression by manipulating the throw-off through the linkage (if the throw-off mechanism itself isn’t broken) which will basically lock it on impression until you get the lever and linkage fixed. If you do that remove all packing before turning the press over and check carefully how much there should be for good impression.


I was able to lift the lever up by hand without too much effort. It has a clean break down by the base which shouldn’t be too hard to weld together.

I was wrong, the press had been “on impression” the entire time. My current packing is 6 140lb cover sheets. It seems like a lot, but that’s the packing it took to make a clean impression, the one pictured.

Your press is not on impression from the photo I see.

You have made it work with the packing.

A press like you have will push the image through the paper if you are on impression.

It just hit me, you press is running backwards. Check your motor.

I had this problem when I started in the 60s. The press looks like it running correct, but it not push with force on impression, that why it not printing sharp.
