In Booth #3044 during PRINT13, RBP will introduce Unitrol® 2500 fountain solution, updated to run on newer, high-speed sheetfed presses.
Sheetfed, commercial and packaging printers running newer high-speed presses are demanding updated fountain solutions to replace alcohol or alcohol replacers. RBP Chemical Technology, Inc., Milwaukee, Wis., (www.rbpchemical.com) is responding to this need with the launch of its new Unitrol® 2500, a one-step sheetfed fountain concentrate during PRINT13, September 8 – 12, 2013, McCormick Place, Chicago, IL. RBP, a nearly 60-year-old veteran developer, manufacturer and distributor of high performance chemicals and consumable supplies, has created the one-step fountain concentrate to run on all types of sheetfed presses.
As a supplier of HAL fluxes to the circuit board industry, RBP Chemical Technology® researchers were very aware of the drawbacks of conventional, halide-based products. High corrosivity, frequent equipment maintenance, time-consuming solder skimming, deficiencies in solder coverage, dull solder and environmental issues all led our product development team to find a better, more reliable product for the HAL process.
The shop is swamped and orders are pouring in. There just isn’t any time to clean the equipment or scrub a tank — right? WRONG — a critical mistake made by some PCB manufacturers is to wait until a process is out of control rather than perform regular preventive maintenance (PM) procedures throughout their operations.
More and more board shops are interested in running the tin stripper on a feed and bleed system. This method gives more consistent performance and reduces the downtime for dumping and changing the solution. The system can be controlled either by specific gravity or panel count as illustrated in the charts below.
Imaging fine lines is easy; developing fine spaces is hard.
With the standard circuit resolution quickly moving below 5 mil lines and spaces, pressure mounts on the developing process, challenging manufacturers to find new ways to keep consistent quality and high yields.
Computer-to-plate (CTP) printing proves its value to printers every day. The latest refinements in CTP let you spend less for pre-press and plate-making and get your plates on press faster.
The skirmishes are everywhere – roller glazing and stripping, white blankets, pH and conductivity drift, plate blinding and picture framing. Calcium buildup problems are popping up all over the pressroom. Sometimes it is only a little flare up like plate blinding, quickly taken care of by replacing the plate. But other times it is an all-out war with buildup on rollers and blankets causing poor print quality and lost press time.
My outer layer resist stripper process works fine until I run jobs with very fine lines and spaces. The dry film sometimes gets trapped between circuits causing etching problems. How can this situation be avoided?
In lithographic offset printing it is necessary to keep the non-image areas of a plate moistened with water so that they will not accept ink. During platemaking these non-image areas are desensitized, usually with a thin absorbed film of gum Arabic and desensitizer so that they prefer water instead of ink.
Chennai-based Kapoor Imaging announced its technology transfer deal with RBP Chemical Technology to set-up a plant for producing press room chemicals in India. According to the contract, RBP will provide technical know-how and chemical formulations to Kapoor Imaging for producing the chemicals at their recently expanded factory in Chennai.
