Limitations in the BK5030 system
• The Plockmatic BK5030 Production Booklet Maker is suited for customers whose book-
let making needs will not exceed an average 20,000 booklets per month.
• If sheets entering the BK5030 is not uniform and square the booklet quality will vary
accordingly.
• The maximum recommended number of sheets that can be folded without stapling is 5
sheets of 80 gsm. If there is very low friction between the sheets, running non stapled
sets may be difficult.
• Staple position may vary on the spine when being square folded with the BookFold
BF5030 module, especially on thicker booklets. Moving staple position so staple is cen-
tered on the spine will reduce this phenomenon.
• Staple may be radius shaped (bent) when running with Book Fold module. Moving sta-
ple position so staple is centered on the spine will reduce this phenomenon.
• Covers may show marking along the spine of the booklet from the clamp in the BF5030
module. The more pages in the booklet, the more evident the marking. The use of “pro-
tection sheet” eliminates this marking.
• For some white coated stock, such as “Silk type” two sided coated paper, occasional
fold roller marks may be observed on the “top side” of the book. . The use of “protection
sheet” eliminates this marking.
• Simplex booklets are not supported.
The double feed sensor should be turned off when feeding cover 200 gsm or more from
the CF5030 module. You may also have to turn off this function if you have heavy dark
area coverage or covers with different images on them.
• For jobs with multiple sheets of 200 gsm or heavier the BF5030 module is recommend-
ed for an acceptable output. If BF5030 module is present in the configuration the Book
Fold shall be turned ON or feed problem at output may occur.
• The protection sheet function may not function correctly with thicker booklets. If there is
very low friction between the protection sheet and the set, functionality may be poor.
• Heavy weight media will show image crack in the spine, pre-crease the cover to avoid cracking.
• Thick books made from coated stock with high friction between each sheet may show
permanent “wave like” deformation of the sheets.
• Marks from the fold knife may appear on sensitive media on the inner sheet.
• Marks from side guide motion may appear on sensitive media, the use of protection
sheet eliminates this.
