In print production, page crawling is an important issue affecting the quality of finished products. So what is page crawling?
Generally speaking, when folding, because the paper has a certain thickness, the page folded inside the booklet will have a certain shift compared with the page located outside. If it is not processed, the body content of the inside page will be Cut off, this phenomenon is called creeping phenomenon.
Check Preps (Preps is the ideal imposition layout tool for commercial printing, which provides the flexibility needed to build a workflow to meet your unique requirements. Preps can combine the combined PostScript, PDF, EPS, DCS, TIFF Large version, no manual work required. The finished version can be exported to any PostScript-compatible device, such as imagesetter, CTP device, print-on-demand printer, digital printer, large format imposition proofer or laser printer.) , the definition given is:
When the page is folded, the image area of ​​the internal page generally slightly exceeds the image area of ​​the external page. This phenomenon is called climbing out. The amount of climb in the job is affected by the number of folds and the thickness of the paper.
In a saddle stitching job, because each of the folded pages is located inside the other folded page, the increased thickness of the folded pages causes the inner posts to be beyond the range of the posts they are in. In a binding job, crawl out pages that are restricted to each individual post.
In Preps, climb out by applying white edges. When a job is printed, the applied amount of compression moves the image area on the page in the specified direction.
So, how exactly do you calculate the amount of creep?
First, determine the amount of compression to apply:
Approximate formula: (number of sheets / 4) x paper thickness
note:
The value used for the number of sheets depends on the type of binding:
If it is a perfect binding, it means the page of each post.
If it is a saddle stitch, it is the page for each entire book.
The value of the paper thickness is in microns. You can measure it with a micrometer or use the metrics provided by the paper vendor.
The precise method:
Make a folding sample with the same paper and the same equipment you plan to use for your work.
Use a precise tool to measure the amount of climb.
Measure the difference between the outer edge of the outermost page (front) and the outer edge of the innermost page.
Next, apply the amount of compression
Open the job and from the Job menu, choose Layout Details.
In the White Edge (Climb Out) area of ​​the Layout Details dialog box, enter the amount of internal and external. Note the following:
A positive value is to move the image area toward the binding edge of the page.
A negative value is to move the image area away from the binding edge of the page.
For perfect binding or duplex templates, the internal amount is applied to the innermost page of each post.
The specified amount is applied to the largest post in the job, and the amount of compression of any smaller post is relaxed proportionally so that all the posts are matched in size after binding.
For saddle stitching templates, the internal amount is applied to the innermost page of the book.
Click OK.
Preps then calculates and applies the distance the image area on each page remains to move based on the total number of job pages and the template binding style.
