Scanner C 299 - C 399 - CP 340/345 - DC 350
 
         
 
With the development of the Chromagraph C299 scanner in 1977, as an entry-level model, microprocessor technology with the Intel 8080 processor was used for the first time on a large scale in Hell's products.

The processor is responsible for the machine control and the calculation of the correct film exposure. (Film linearization)

Another essential feature is the lack of a film cassette: the entire device (or just the film exposure cabinet) must be installed within a dark room.

However, the color calculator is still based on analog technology.

As with all previous models, the exposure speed of these devices is 10m / sec.

Other variants such as:
C 299L; C 399; C 399 L will later be equipped with a laser exposure unit and electronic screening.

  The CP 340 and CP 345 scanners represent the so called "poster" scanners with a development history similar to that of the C 299 / C399 in terms of device control, screening technology and system connection.
This type of device can scan much larger originals and expose films the size of a poster.
The writing format of the CP 340 is 110 x 128.5 cm

  The latest version of this machine series are the
DC 380 T and the CP 354T, equipped with a digital color calculator and the possibility of a system connection. This means that these devices can be used both as system scanners and system recorders.

  While the mechanics of the DC 350 is based on the more than 1000 times proved
                         DC 300 B
     (the workhorse of repro technology)
the electronics are adapted to the state of the art in several steps. Also to be mentioned here:
- digital machine control
- digital screen calculator with
    rational; irrational and special screenings
- ChromaCom system connection
