Imagination and creativity	top ^
Imagine an enlarger that lets you crop to any size you want in full daylight operation
Imagine an high quality video analyzer that is an integral part of that enlarger.
Imagine a connected RA4 processor that delivers a dry print in 5 minutes (or less).
Imagine the Cropping Videolab by Polielettronica.
It has has the cropping versatility of an enlarger, the 1^st shot capability of a video analyzer and the speed of an automatic printer.
Only your imagination is the limit to what this printer can do.
Mini labs, "People" labs, Commercial labs and finishers alike can benefit from the custom cropping and excellent first time print capabilities this system offers.

Monitor cropping system	top ^
In the normal cropping system, a gray frame of variable size is generated on the monitor. The frame moves according to the magnification factor selected and is automatically related to the real size of negative and paper.
By pressing the UP and DOWN buttons, the magnification displayed on the monitor may be changed over a continuos range. When the desired magnification is reached, the computer selects the proper lens, paper deck height and focuses in an instant.
Of course, when changing lens or magnification the computer calculates new linear factors in order to modify exposure time; paper reciprocity correction is stored in Videoscan memory.
Because all lenses are matched for transmission and color, there is no need to compensate for lens changes.
Set-up data is backed up in a small memory card. Data may be restored from the card to the printer at any time.
The "Cropping Videolab" has been optimized for any RA4 paper in use today at a production speed exceeding 100 meter/hour (65 inches/minute) and 150 meter/hour (98 inches/minute), upon request, for high production capacity.
All processor functions 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.

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.
	Alarms are incorporated for empty replenishment tanks and full overflow tanks.

Writing System

The back of print Writing System, is available in two versions:
Filtration values only. This allows you to write the order number, print number, filtration values and enlargement magnification.
Complete. In addition to the above mentioned values, the full system can print a message typed with an external keyboard.
Please remember that the Writing System operates correctly only if the transport is greater than 150 mm.

Photocard Mask

Allows personalized printing, with text or graphics, from a negative or transparency. The unit has a control panel for corrections independent from text or graphics density and color.
Standard size : 11x18,5

Frame Grabber

Allows saving of up to three different image sections or one full image.
The operator may now have permanent references to achieve consistency in a common subject.

100 Hz Monitor Frame Grabber

Has the same characteristics as above, but the 100Hz monitor improves the overall image quality of the display.

Order Separator

Allows to separate the orders during production in 10x10 and 10x15 formats.

RGB to PAL or Y/C Converter

Allows connection to a videotape or a PC, e.g. for picture indexing or generic imaging.

Densitometer

Reflection densitometer for a better and more complete printer setup.

Video technology	top ^
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.
Use the UP and DOWN buttons to adjust magnification over a continuos range. The gray frame tracks in and out as you change magnification, always showing the correct cropping. You can adjust negative positioning and rotation with the movable negative stage.
Press the "1" key again to return to the Video Analysis mode.
Activate the Autoscan function by pressing the top joystick button.
The scanner will set the optimum color and density.
If you wish to change the color or density after viewing the monitor image, you can use the joystick to do so.
A solid state CCD telecamera is used for viewing and analyzing. Because the same light source is used for analysis and printing, there is no need to readjust for specific film types and balances.
With 100 independent channels on the computerized videoscan section, the operator can organize sizes, film, paper emulsion and many other functions.
The additive 2000 watts lamphouse ensure adequate speed and sharpness
The lens section is an 8-position turret: 7 of these position are occupied by 28, 35, 50, 60, 80, 105, 135 Rodagon Rodenstock lenses.
The eighth position, located inside the bellows, is used for a 150 mm lens with fully automatic focusing so that it is possible to print 1:1,23 magnification and upon request 1:1 only from 6x7 negative size.
The turret is fully automated, and when the correct cropping on the monitor is reached, the computer selects the proper lens focus almost instantaneously.
Individual focal length lenses are used and auto-focused throughout their range rather than using a zoom lens, so that sharpness is never compromised.
The focusing is achieved within 1/100^th of a millimeter of accuracy.
