We are pleased to introduce the 20"x30" Cropping Videolab.

This new large size integrated laboratory is born from the connection between the 20"x30" Printerlift and an RA4 processor for 20" paper width running at 100 meters per hour (65/inches/minute).
The 150 meters per hour (98 inches/minute) paper processor is available as an optional.

All the best characteristics of the Cropping Printerlift have been preserved and improved.
For example the left paperbox, the paper automasking curtains and the independent blades for bordered prints, new look and extreme compactness so that it is very easy to accommodate it in a shop.

The 20"x30" Cropping Videolab offers State of the Art technology in photographic printing.

It enables you to work in complete daylight, with all the versatility and features of the very latest top quality automated enlarger and the speed of a printer.

With 100 channels to set up any film or paper emulsion with precision, the new VIDEOSCAN analyzing system makes this printer one of the most versatile in the industry today.

No matter what type of  photography you have: portraits, weddings, commercial or finishing, the Cropping Videolab can produce high quality enlargements.

In short, let your imagination be the only limit for the use of Cropping Videolab.

The optical system, by Rodenstock, is computerized and fully automated.
It incorporates a lens turret with 8 positions, ranging from 28 mm. to 135 mm. lenses.

The eighth position, located inside the bellows is used for 150 mm. or 180 mm. lens, also in the autofocus mode, and generally used for 4x5" negatives.

The turret is fully automatic: when the correct cropping is achieved on monitor, the computer selects the correct lens and focuses instantly!

Individual focal length lenses are used and autofocused throughout their range, rather than using a "zoom", so sharpness integrity is never compromised.

Focusing is achieved by computer formula and within 1/100th of mm. of accuracy.

Video technology

A solid state CCD telecamera with zoom and coupled with an high quality monitor is used for video analyzing section.

A very useful feature is the autoscan. Pressing the top joystick button will give you an automatic display on monitor, that you may want to use or correct, by using the joystick itself

Lamphouse

The lamphouse has no moving parts and light output is produced by 8x250 W printing lamps.

Automatic monitoring in case of lamp burn out is provided with a diagnostic led pointing out faulty lamp(s).

The machine stops printing until the lamp(s) are replaced.

A densitometric control system keeps light intensity and color constant!

The same lamphouse is used for both printing and analyzing. The same light intensity and filtration values are used so that there is no translation needed.

The diffusers (light boxes) turn automatically under computer control.

Monitor cropping system

In the cropping system, a gray frame of variable size is generated on monitor.
The frame moves according to the magnification factor selected and is automatically related to paper and negative size.

By pressing the UP or DOWN buttons,  the cropping frame will change until the desired crop is reached.

The full negative is on display at all time so that you may see the cropping needed just by moving the complete negative holder assembly.

When cropping magnification is reached, the turret and paper deck move and provide proper focus and size.

Needless to say that when going up or down the computer adjusts for reciprocity.

Another feature is a lens offset to match all lenses for color and density.

Set up data is backed up on a small memory card. Data can be restored from the card at anytime.

Example of cropping

The "Cropping Videolab" has been optimized for any RA4 paper in use today at a production speed exceeding 100 m/h (65 inches/minute) and 150 m/h (98 inches/minute) optional, for high production capacity.

All functions of the processor are monitored by computerized controls that can be checked by the operator, and modified as needed. Some are chemical temperature, dryer temperature, individual replenishment for each chemical, automatic morning start-up, automatic dryer switch-off at end of process.

In practical operations

Insert a negative in the printing gate.

Press the "1" key on the keypad to set the direct video cropping mode. A gray frame surrounds the image in the monitor, indicating the area that will appear in the final print.

Press the "1" key again to return to the video analysis mode.

Paper processor

The processor is available in the standard 100 m/h (65 inches/minute) model and in the optional 150 m/h (98 inches/minute) model.

All RA4 models have a microprocessor control with the following characteristics:

Three independent developer time channels (normal, duratrans, special jobs)

Independent temperature control for developer, bleach and dryer

Dryer standby (low consumption mode)

Independent control for replenishment circulation of all three integration pumps

Automatic and adjustable speed control

Quick change from chemical (waterless) to water wash

Developer, bleach and dryer overheating alarm, developer and bleach tank low level alarm and low level wash heater circuit.

Replenisment-overflow group, has 30 liters tanks for replenishment and 20 liters tanks for overflow.
