1 – Introduction to Web Presses
What is a Web Press?
The first step is to develop an understanding of what a Web Press is. In essence, web presses are rotary presses that continuously print on a roll of paper. Paper is fed automatically from a large roll, and the web press processes the printing on it prior to it being cut. The Web Printing process is utilized where there is a large scale requirement of printing (but not on heavier cards).
Web Presses can be categorized into two sub sets:-
Cold-Set Web Presses :-
While at first glance these presses are identical to the heat set web printing presses, they utilize a much faster drying ink. This process is not suited for coated papers as it requires a substrate that will absorb the ink. There is no additional heat used to dry the ink.
Application: newspapers and offset sheets:-
Heat-Set Web Presses:-
Again, these presses are similar to cold set web printing presses except that they include, in addition, a heat tunnel which is used to flash or shock the ink to a dry stage prior to the exit of the ribbon of paper from the press. Almost all heat-set web presses offer finishing services on the press such as perforation, gluing, scoring, slitting, die-cutting and folding. This equipment can achieve speeds as high as 20,000 to over 100,000 impressions per hour.
Application: cheap brochures, leaflets, sell sheets, flyers and inserts :-
Applications of Web Presses :-
Web presses are best suited for producing massive volumes of high quality prints with minimal maintenance and economical costs. They can be used for printing newspapers, books, magazines, brochures, leaflets, flyers, stationery, etc.

3. Manufacturing and Installation Experience :-
Would you ever allow an inexperienced person to make your food or cut your hair or fix the plumbing of your house? No! The thing is that experience matters. The longer someone works in a field the more they accumulate practical knowledge and certain tips & tricks. The longer a Web Press Manufacturer has been in the business the more likely they are to be reliable.
This has a twofold reason. Firstly, if they have stuck around for this long they must be doing something right. Secondly, in all their years of working they would have encountered multiple problems and consequently learnt better ways to manufacture. They possibly use better quality raw materials, better engineering and so on. The same applies for installation experience. The more someone does something, the more adept they become at it. You are likely to encounter fewer problems with someone who has a long and rich experience in manufacturing and installation of Web Presses.
4. High Quality Metallurgy Parts :-
Going back to the basics, the better the quality of the individual parts that are being used the lower the expected wear and tear will be. This in turn will directly translate into longer lifetime of the Web Press you are going to so heavily invest in.
5. High Quality bearings, sleeves and gears :-
While these might seem like small parts and not worth checking, it is the function of these parts that determines the amount of time your press will spend off-road. Obviously, if you invest a lot of money into your business, you would not want your primary machine to malfunction often. Save yourself the trouble and invest in a machine with high quality parts. Along the same vein, find a manufacturer who offers good customer service to save yourself a lot of hassle in the future.
