• ImagOn developer 
  • 1 level tsp.(10 grams)of Soda Ash 1 liter water 
  • Add soda ash to a small amount of hot water until the powder dissolves. 
  • Add room temperature water to dissolved soda ash solution to make a volume of 1 liter. 
  • Working temperature of the developing solution should be between 65-70 degrees F. 
  • Add developing solution to photo developing tray.

Intaglio Type: Mylar On

Non-etch method used without top protective Mylar layer left on the ImagOn film.   More contrast. 

Materials:

  • Plate laminated with ImagOn 

Overview:

In the Intaglio-Type technique, after the ImagOn is laminated to the plate, the artwork is exposed to the ImagOn with either this top Mylar layer in place or with this Mylar layer removed. Not only is there a great image making difference between these two techniques but also the methodology for using them differs.

Recommended procedure:   


Prepare Plate 

Adhere ImagOn to plate 

.

Decisions

  • At this point the ImagOn laminated plate has a top protective Mylar layer which may or may not be removed before exposure. The decision to leave or remove this top protective layer will be based on the desired effect required in the final print. The difference between leaving this protective layer on, before exposure to the artwork, to the final printed image is that this image will have greater contrast and less detail.  Taking the Mylar off before exposure will result in a greater detail and less contrast.  If the Intaglio-Type-ON technique is used then the top Mylar protective layer is left on the ImagOn film before exposure to the art work the procedure is straightforward.  

If you have a low contrast negative and you wanted a finished image with more contrast then you would use the Intaglio-Type-ON technique.     

There are some fragile type stencils, such art work made from laser printers and hand drawn or painted art work that will necessitate leaving this protective layer on because of the potential for this kind of art work to stick to the ImagOn emulsion.  The longer the ImagOn coated plate is left to dry the less the likelihood of the artwork sticking.  
If you still wish to expose other kinds of art work, other than a lith film positive, rub a small amount of vegetable oil on to the art work and to the ImagOn emulsion before placing it the vacuum exposure unit. This action helps to prevent the artwork from sticking to the ImagOn emulsion.
  • If the Intaglio-Type-ON technique is used then the top Mylar protective layer is left on the ImagOn film before exposure to the art work the procedure is straightforward.  
      
    If on the other hand you had a low contrast negative and you wanted a finished image with more contrast then you would use the Intaglio-Type-ON technique. Due to the unique nature of ImagOn photopolymer film both ON and OFF techniques allow another level of image manipulation that has until now been unavailable.  
Health Warning 
Rubber gloves RECOMMENDED for the development procedure. Repeated use of developing solution can dry out the skin and cause a dermatitis reaction on the hands. 
Health Warning 
Eye protection advised. 
The developer is an alkaline solution. Do not splash the developing solution into eyes. 

Health Warning
Dry without heat
