Applications

Alfa films are designed for imagesetters and scanners with;
HN-RD: HN (633 nm) and RLD (630-680 nm) output devices.
IR: Infrared laser (780 nm) imagesetters or equiprnent using laser diode sources
LED: Light Emitting Diode (670 nrn) output devices.
AR: Argon ion (488 nm) laser light sources.
CMR: Camera Back. R.A projection.
DLC: Day light contact.
DLD: Day light duplicate.

    Storage

    Store in a cool, dry area, preferably below 21°C and 55% relative humudity. Prolonged storage under warm and / or humid conditions may shorten the product's shelf life.

    Processing Chemical

    Developer Dilution* Repl. Rate Temperature Time
    Alfa DEV 1+4H2O 350 cc 35°C 30 sec.
    Alfa FIX 1+3H2O 400 cc 35°C 30 sec.
    KPG RA2000 1+4H2O 350 cc 35°C 30 sec.
    KPG RA3000 1+3H2O 400 cc 35°C 30 sec.

    Some Guides for Trouble Shooting

    Effect Probable Cause
    Low density Developer time too short / Developer temp too low / Wrong dilution / Insufficient replenishment
    Base fog Developer time too long / Wrong dilution / Developer temp too high / Bath contaminated
    Yellow staining Bath contaminated with fixer / Fixer temp too high
