FLEXO Magazine : July 2008
IGT Based on its Fl ink tester, the Fl UV has an integrated UV dryer, where the curing is done immediately after the printing. It is fully suited for use within the frameworks of ISO 2846-5 and IS02834-2 for the mea- surement of color of flexographic inks and test prints. The integration of the UV dryer makes this larger than the standard IGT FI. The dryer is positioned immediately after the printing section, so that a mini- mum time between printing and curing is realized. Here also, a flat substrate carrier has been chosen, so that hard and rigid materials can also be printed. The engraved roller is driven separately. The speed of the engraved roller can be adjusted, so that an optimum filling in of the cells can be reached before printing. Consequently, and in combination with the possibility of using several pre-inking revolutions on the photopolymer, the whole print of more than 40 cm can now also be used for measurement. The UV dryer is equipped with a UV lamp of 7 SOW generating A, Band C class ultraviolet radiation. The energy of the lamp can be adjusted from 70 to 100 percent. It has a maximum lifetime of approx. 1000 burn- ing hours. KODAK The Kodak Flexcel NX digital flexograph- ic system, previewed in the November issue of FLEXO, was made commercially available for the first time at drupa 2008. The integrated digital platemaking system includes a laminator, a thermal imag- ing layer (TIL), a plate imager, Kodak's Squarespot imaging technology and Prinergy workflow system. Laminating the TIL directly to the plate prevents oxygen attack, enabling the formation of stable, full amplitude, flat-top dot on the plate. Also, this process helps ensure that plates do not plug with ink as quickly as on other plates. (See page 56 of this issue for a case study.) LOHMANN CORP. Targeting smaller printruns, Lohmann Adhesive Tape Group revealed a new product range for the high-quality post print corrugated. The two new versions of DuploFLEXI!Ð CB meet the needs of the post print industry directly. One is a single-sided adhesive foam tape and the other is a non-adhesive product with a foam on one side and a PET-liner on the other side. For both products, the foam can be offered in various thicknesses. The main advantages are the ability to absorb print vibrations. Other new products shown included the DuploFLEXI!Ð HP 5 se- ries and the DuploFLEXI!Ð 3 and 4 series of tapes. The former is a high-performance plate mounting tape range and is suited for very special print jobs, while the latter plate mounting tapes were developed for the label printing industry. ROGERS CORP. A new line of cushion mounting mate- rials for corrugated post-print applications was introduced: Efbak Cushions. These products are designed for use on general purpose corrugated applications of line and solid work with simple combination screens. They are an alternative cushion for mid-range print quality jobs providing standard quality print results, lower dot gain, and maintaining high solid ink den- sity, allowing consistent print results over an entire pressrun. Based on open-cell urethane foam technology, Efbak Cushions build thickness on the cylinder, while also providing cushioning and absorbing vi- bration to reduce gear banding in the cor- rugated print process.
