Elanders Poland specializes in web offset heatset print. Our color offset heatset presses print at a speed of up to 55,000 sections per hour. This means we can produce high volumes of magazines and catalogues with excellent quality very quickly.
If you answered “yes” to any of these questions, your project is most likely suited for web printing technology. Contact one of our specialists today about your project for personalized recommendations regarding the best technology options available to you.
The shorter cover effect occurs when two technologies are used for a project (e.g., sheet-fed printing for the cover and web heatset printing for the inside pages). During web heatset printing, the paper shrinks slightly due to the high temperatures in the heating unit. After binding, the paper takes in moisture from the air, regains volume, and expands, resulting in a roughly 1 mm size increase. This effect is common and is almost invisible to the end user.
Ideally, the fibres that make up the paper in a book or magazine will be aligned vertically (from top to bottom). For sheet-fed printing, it is possible to buy paper suitable for a project’s final size in sheets with the correct fibre alignment (short or long grain). In a reel of paper, fibres are uniformly arranged in one direction. Therefore, some printing formats will achieve the correct vertical fibre alignment, while others will have a transverse fibre alignment. Paper behaves differently when its fibres are transverse. Transverse fibres are almost invisible when used with saddle stitching or hard covers, but they are more visible when perfect binding is used. At Elanders Poland, we will inform you if your selected format must be produced with a transverse fibre.
The final cost of a project printed via offset printing depends on the type of offset printing used. Most of the several thousand printing houses in Poland use sheet-fed machines; only a few can boast about offset web presses, as these machines are very expensive and very large, requiring an immense amount of space in a production hall.
Several distinctive features set heatset web offset machines apart from sheet-fed machines. A major advantage is their printing speed, which is 4–5 times faster than the speed of sheet-fed printers. Additionally, automatic folding systems are built directly into the machines, turning printed sheets into finished products. This eliminates the need for drying and additional folding processes, which are essential for projects that have been sheet-fed printed. A sheet of paper has a specific size, so it must be folded to obtain a specific number of pages or format. While the A4 size is the standard format used in web offset printing, it is possible to obtain various final formats depending on the technical capabilities of a given machine. Finally, large quantities of paper on a reel are cheaper than the same quantities of sheet paper. Because of these factors, web offset printing is time-saving and economical, resulting in much lower unit prices for customers.
Offset printing uses technology that allows for the best colour reproduction. Sheet-fed allows the use of additional Pantone colours, such as gold and silver, web-fed offers CMYK reproduction. Thus, exclusive magazines, catalogues, albums, and other promotional materials of the highest quality can be printed to reflect a company’s desired image.
When using offset printing, it is necessary to keep the minimum input in mind. Sheet-fed offset printing works best when at least 1,000 sheets of one layout are printed. On the other hand, web offset printing presses require at least 15,000–20,000 copies to be profitable.
When a project is ready for printing, it is necessary to decide what type of paper will be used. Sheet paper ranges from 60–350 g/m2. Higher paper weights are used in the printing of books with lower inputs, albums, folders, special catalogues, periodicals, and leaflets. Web offset printing is normally done on a roll of paper weighing 42–130 g/m2, but it ultimately depends on a printing house’s technical capabilities and type of folding. Both web offset and sheet-fed printing can be done on coated or uncoated paper with full range of quality of the paper including the best one (woodfree coated called art paper).
