Bieler Press Photopolymer Platemaking Service
Megaloceros, Aaron Horkey, Dead Arts Publishing, 2010. Printing at The Bieler Press.
Gerald Lange of The Bieler Press has printed with the photopolymer plate process since 1991 and provided plates for the contemporary studio letterpress community since 1995. Offered to letterpress printers in the Los Angeles environs are professionally processed premium-grade plates for today’s common bases with fast turn-around (aka RUSH). Plates are generally processed and shipped (M-F) same day as receipt of film or available via convenient 24/7 pickup (any disruptions are indicated in Scheduling at bottom of post).
Professionally processed film negatives are required. Recommended is Tamburello Productions, an online silver-based film negative processing service who supplies a quality product at low cost with free delivery to The Bieler Press (contact Tamburello directly for their payment requirements). Tamburello requires receipt of e-files by 3:00 pm for early morning delivery of processed film the next business day.
* Client must notify via email of pending orders prior to receipt of film as this provides a means of quick, specific communication, and scheduling (unidentifiable film will not be processed). Attach a PDF of your imaging for identification purposes; this also allows for checking of possible technical problems prior to processing. To prevent delays, clients must provide contact information and indicate with order their delivery/pickup preference (with address for shipment), and specific plate needed.*
Photopolymer Plate Specifications:
Currently stocked are the following Toyobo Printight Type K brand plates for use with flatbases. These photopolymer plates are state-of-the-art industrial quality. They are manufactured with photosensitive nylon resin, thus they hold sharp detail and fine lines exceptionally well with no loss of imaging during presswork. These plates all meet the standard letterpress formulated hardness rating of Shore D 67˚.
• KM95GR—steel-backed at .038" thickness—highly recommended for use on production Vandercooks or Heidelbergs with properly configured magnetic base, e.g., an industry standard Bunting Magnetic Cerface Flat Base ground to .880" (no interlay required). This is the plate used at The Bieler Press for all of its production (see pic above). It is especially recommended for large format pieces and/or difficult imaging. This plate can also be fitted to a Patmag base (or similar non-industrial economical base with magnetic top sheeting) with appropriate underlay (+/- .022) and interlay [such as 3M’s 75 Spray Adhesive].
• KM152GR—steel-backed at .060" thickness—specifically recommended for use on job platen presses, such as a C&P or Kluge, and smaller platens, where roller height issues may be of concern. Normal configuration for a Patmag base or fitted to a Bunting Magnetic Cerface Flat Base ground to .858".
• KF95GC—polyester-backed at .038" thickness—common configuration for economical non-industrial aluminum flatbases such as the Boxcar Base, the ēlum Eluminum, or others of similar non-magnetic construction. Plate includes attached .004" transparent film adhesive interlay [from BiesSse Tape Solutions]. Requires appropriate underlay if used on any flatbase measuring less than .875" +/-.
Maximum plate size (including required margins, crop marks or other registration devices) is 16-1/2 by 23-3/8 inches (A2). Plates are furnished with unaligned edges cut approximately 1/4 to 3/8 of an inch (+/-) margin around imaging (if more or less edge border is required client should request this with order and provide adequate room on e-file).
Imaging and Film Negatives:
B/W line art furnished for platemaking must be in the form of high-quality imagesetter generated silver-based film negatives with discernible emulsion side, a resolution of 2400 dpi (highly recommended), and made as RREUs (emulsion side up/right reading). Select EPS or Press Quality PDF when submitting e-files to your film processor. For difficult imaging requiring dot patterns, such as photographs or tonal backgrounds, please inquire.
If client requires multiple plates cut from negatives, imaging should be separated by a minimum of 3/4 of an inch and aligned for linear cuttings in either direction. Cutting schematic should be emailed via PDF or enclosed with film negative. In all cases, to avoid problems please leave at least half an inch margin at outside edges of the film negative.
Negatives and all other materials are returned to client. Negatives are trimmed to facilitate platemaking.
