How does stock thickness / spine thickness affect the way a perfect bound job is done?
Stock thickness can greatly affect the run speeds of the machine used to produce it, with thicker books requiring slower speeds and greater accuracy in setting up the trimmer. Thicker paper stocks usually run a bit easier, but the machine requires more workers to keep it full as it can run out of stock much faster. This may not be an issue for shorter runs, but thicker paper can certainly add time and cost to larger runs. Generally, the spongier the stock, the more of a challenge it can be to perfect bind as it does not compress well unless under pressure (in a clamp for example). For thicker products, this can be an issue and cause multiple passes on the perfect binder. It is recommended to consider this when selecting the paper stock and avoid the more spongy stocks for thicker books or publications. Question: When are glue adhesion issues most likely to occur? Referring back to the previous question, stock thickness also affects adhesive selection. Heavyweight coated stocks will mak
