Metal Decorating is one of the areas where G Technologies have developed specific drying systems to suit this type of printing.   Machines which have systems fitted to them include: Crabtree, KBA Metalprint and Fuji Kikai.    Incorporating both interdeck, and post delivery systems, fluid or air cooled, G Technologies can furnish a system to suit virtually any metal decorating press, current or previous generation.     The lamp and reflector are the heart of the drying process, and described below are the three types of units offered by G Technologies.

 

D Q Reflector

DQ dia

The new 'DQ' dichroic reflectors by G Technologies have been specifically  designed to dry UV inks and varnishes on metal by maintaining high production speeds and low temperatures when printing. They are manufactured in aluminium and are installed either, interdeck, between units or on a conveyor after the last print unit where interdeck installation is not possible. The vacuum created by the cooling fans as well as the pressured circulation of the cooling fluid, and the anti-reflection protection guards assure low operation temperatures and absolute safety to the operators as well as the vicinity around the machine.   The rotation of reflectors is synchronized with the production of the machine allowing the lamps to reduce power during production pauses. Reflectors are easily removable for maintenance.   Special quartz barriers (optional), treated with dielectric multilayer material can be incorporated between lamp and substrate in order to obtain an excellent UV ray reflection and a considerable IR radiation reduction. The reflectors can be supplied with specific powers up to 240 W/cm and 2000 mm. arc.

 

 

RQW Reflectors

RQW diaUnlike the DQ reflectors the new RQW reflectors have been designed by G Technologies to meet UV drying requirements on metal decorating offset machines where Interdeck installation is not possible. They are extremely sturdy and made of four anodized aluminium extrusions with a light outer case. The inner  surface is covered by special dichroic mirrors able to reflect 98% of UV  radiation and absorb more than 85% of IR radiation. The RQW reflectors are cooled by air forced through the inner reflective housing which ensures an efficient and economic elimination of heat and ozone. The design of the inner surface specifically promotes reduced  contamination from volatile particles given off by the ink or varnish  as well as dust. The reflectors can be supplied with specific powers up to 240 W/cm and 1700 mm. arc.

 

Q-EXTREME Reflectors

Q EXTREME dia

The new Q-EXTREME reflectors by G Technologies have been specifically designed to dry photosensitive UV inks and varnishes on metal by maintaining high production speeds and low temperatures when printing. They are normally installed on off-line equipment and like their stable-mates, manufactured in aluminium, and synchronized with production of the press and allows the lamps to reduce power during production pauses or stops. The vacuum created by lamp and reflector cooling fans as well as the anti reflection protection guards ensure absolute safety to operators as well as the working environment around the machine. The reflectors  can be supplied with specific powers up to 180 W/cm and 1700 mm. arc.
