I've been reading a lot of comments on his forum about the advantages and disadvantages of PUR vs EVA glue in perfect binding. Most of those comments are quite a few years old now, and it has been suggested that modern EVA glues are almost as good as PUR and certainly good enough in 95% of...

I have heard other people recommend lowering the tension, which I agree helps. But I thought the main cause of curl is the fact that paper and standard laminates expend and shrink at different rates, so when a book warms up or cools down and/or the relative humidity changes, the paper will...

Perhaps refilling with EVA glue granules would eliminate some of the possible issues?

For my perfect bound book covers, I am laminating single sided, with a Nylon based SuperStick laminate, sourced from the US (link). The reason I use Nylon based is because the standard laminates tend to be more prone to curling in single sided applications, whereas the Nylon laminates...

This is very helpful and exactly what I was looking for, thank you!

I am trying to calibrate a Duplo UltraBind PUR 2000, but without much experience or a technical manual with specs I am left with a lot of guess work. Does anyone have a technical manual for this machine? Perhaps for a similar machine that I can get a few clues from? For example, I am wondering...

Do you know the name of this manufacturer/supplier, or how to get hold of their cartridges?

The plot thickens. I had settled on one specific paper, Polar Offset. The rep sent me a sample packet a few weeks ago and it has been sitting in my workshop, uncovered, for weeks and stayed perfectly flat. So I thought this paper would work well for me, ordered a larger quantity, and started...

I have come to the conclusion it's a combination of several factors: temperature, humidity, rapid changes in temperature/humidity and paper type/quality. One type of paper, Polar Offset from the UAE, which btw is the cheapest of all papers I've tried, has been sitting in my workshop for weeks...

I am currently trialling Munken Print paper, and it looks promising. In researching what makes this paper different, I found this little piece of info: Can anyone confirm this from experience? If this is true, then it would help me in my search for the most stable paper to use in a challenging...

A friend suggested wrapping each book individually as soon as it comes off the press. I have seen this done by some publishers/retailers. It adds a bit of elbow grease, but the cost is minimal. Is anyone out there doing this, to protect their books? Shrink wrap, kraft paper, ..?

Yes, paper grain is parallel to the spine. Printing on SRA3 LG, 4 up. Same environments, both heated when the temperature drops. Work environment has a dehumidifier, which I only run when the air gets really humid. Yes, a new ream of paper, when opened up without printing on it, will go wavy...

I have tried that, he did not have any solutions or advice, apart from assuring me that the paper I am using works fine for other printers. I am in the process of talking to a different supplier. I also contacted the manufacturer (in Sweden) but so far no reply.

I does look that way. But then other printers must have the same issue as soon as their paper leaves their controlled environment. Or am I missing something? That's crazy, in a heavily regulated environment, and you still had issues? Thanks btw for the replies, they do help me to put this...

I contacted two of these suppliers (B&F and BJ Ball). One of them was the most helpful (B&F), so I went with them and I found a creamy white paper I really like the look and feel of (Wheki Book White), and other people have confirmed that this is nicer than all the other paper they've seen...
