Pressroom Printing

As a leader in specialty chemicals for the printing industry, we are proud to announce the release of a new state-of-the-art aqueous coating cleaner, AlKalene™ LT. This new product is designed to remove dry ink from press parts in the flexo-packaging industry.

Brighter, more vibrant colors in coldset printing applications? It’s possible with LIQUID GOLD 290 from RBP Chemical Technology . This mildly acidic fountain concentrate was specifically developed to enhance the color brilliance while fighting blanket buildup and piling – the leading causes of duller print images, ghosting, scumming and ink going where it doesn’t belong.

Newsprint and coldset pressrooms choose Liquid Gold 820 fountain concentrate to maximize the performance of a wide array of plates – including processless. Liquid Gold 820 comes in neutral, mild acid, and hard water versions to meet all users’ water conditions and is formulated with special ingredients to keep the non-image area free of unwanted ink, resulting in sharp, clean print, and quick start ups that reduce paper waste. Like all RBP fountain concentrates, Liquid Gold 820 contains the latest in biocide technology to keep the dampening system clean and free of biological growth.

RBP Chemical Technology, the world-class supplier of proprietary chemicals and delivery devices for the coldset printing industry, is proud to introduce the latest in cleaning technology for pressrooms.

The use of processless plates has been gaining traction for some time now.  There are several advantages to using these plates.  The most advantageous is the elimination of the chemistry used to develop and remove the non-image area of the plate.  These chemistries typically have high alkalinity and can be difficult to handle as well as dispose of.  By eliminating this step you remove any potential problems with the processor, associated chemistries and plate waste as the processor is completely eliminated.

With the ever changing plate technology there is always a need for deletion pens in the pressroom.  RBP Chemical Technology offers a variety of deletion pens for the newer plate technologies such as the violet and thermal ctp plates.  You will find that deletion pens come with different chemistries; they may contain various solvents for removal of image area, water, and an acid to etch the aluminum oxide. Picking the right chemistry for the plate you are using is important. Certain types work better on thermal plates vs. the violet plates. Are the plates baked, are they process less types, or violet? Asking the right questions and finding the right pens can make your job a whole lot easier on press.

From poor print quality, the need for more frequent blanket washes, trouble printing solids and “smashed” blankets – piling is one of the more common challenges in today’s pressroom. In fact, many printers today have come to accept piling as a problem that is inherent to offset printing. However, understanding the causes of piling and implementing quick and effective solutions can go a long way in improving print quality and reducing paper waste and press downtime.
