How to judge the quality of exercise books is a problem that troubles many purchasers. As an experienced exercise book manufacturer, Honeyoung will take you to a tour of our factory to see how we check the quality.
1. Cover design of exercise book
The first step of making exercise book is to design the book cover, after completed the cover by design department, our staff will check the bar code, pages, logo printing, spellings, etc. After setting up the layout of the printing, we still need to check them all over again. Check for missing content in the typesetting process, if not, the production can be started.
2. Cover printing of exercise book
Before we start to print, we always check the settings again. More importantly, check the color when printing. Currently, the four – color printing machine is manual ink adding. The ratio of those ink will eventually affect the printing, this is where color difference comes in. In the process of printing, we need to check the color difference between the draft and samples, if possible, make sure there’s no color difference.
3. Inner page printing
Inner page is another important part of exercise book, lots of problems often happen in this phase. Before making the inner pages, it’s also requires pattern making and being double checked. The checking items include: sizes, line interval, line quantity, page header, page footer, margin, etc. After putting into print, the following points need to be noted：First, in the quality inspection, we need to check whether the printing color is consistent with the customer’s requirements; second, check the thickness of the lines, too thick or too thin will not work. Next, check the proportionality and flatness of the lines, qualified exercise book line printing is very proportional; finally, you need to carefully check whether there are broken lines exist, if so, you need to change the printing plate.
4. Binding methods of exercise book
There are many kinds of binding methods, common ways are staple binding, glue binding, sewing binding and spiral binding. No matter what it is, the most important thing is firmness, then it’s appearance. The staples should be straight in line, the seaming should be consistent.
5. Size of exercise book
The finished products are cut by cutting machines, sometimes the cutting machine is not well adjusted, that will renders over cutting. The book will be smaller. But if we cut less, there will be lines less than the edge. Therefore, in the production process, we must always pay attention to the size of the finished book.
6. Pages of exercise book
During the production, the amount of pages should be consistent with the amount on the cover. Qualified exercise book factory will stick to the customer’s requirements. Lack of pages are strictly prohibited in our factory.
7. Paper quality of exercise book
This part includes the quality of cover and inner page. The options for the book cover are ivory board and coated paper with different grammage. For inner pages, we have offset paper, writing paper with different grade and grammage. Good exercise book manufacturer will produce the books according to customers’ requirement.
8. Packaging of exercise book
Here comes the last step, Good packaging can protect your goods during long time shipping. First, we divide those books in batches, and wrap them up in shrink film. Then we load them in carton. If workers misoperated, the film package may be broken, we’ll replace the package. Another kind of packaging is OPP bag, this is more suitable for exercise books with OPP covers, because the shrink film wrapping machine use heat to shrink the film, that heat will damage the OPP cover.
