The equipment needed for the realization of digital negatives is fairly simple. Just a computer, software, image processing, a printer and InkJet Transparency, a digital camera and / or a scanner.
Computer : Whatever brand it is necessary that the capacity sufficient to handle the largest files that you intend using. The use of 2 screens and a graphics facilitates the work of the image. But this is not the subject of this ebook and there are other books and specialized spaces on the net about it.
software : To my knowledge 3 software makes it easy to apply curves and colors to images Gimp and Photoshop (Adobe) Photoshop Elements and (Adobe). I will describe the precise methods of working with these 3 software.
Printer : All inkjet printers can be used, except if there are mechanical problems associated with the use of transparencies. According to the inks will be more or less easy to make negatives for processes that require high density. It is clear that business models are more economical in consumable and also more reliable. But this does not mean that entry-level model is not usable. In addition there are systems that allow continuous feeding of economy and also make use of better quality inks. The ink is an important parameter for achieving the digital negative, a safelight will allow to use more or less ink.
For now many people use the equipment to achieve the Epson digital negative, but it is possible to make negative with any inkjet printer. It is true that 3800 is a good solution for money, but there are solutions such as schedules 1400 with the K3 ink Mr. Cone. But tests that I practice with tracer HP and Canon are very prometeurs.
In fact more than the printer is ink which is important. According to its quality we will be able to manage the inking more finely. J'eclaircirai this technical section in the chapter on the selection of color. Finally
with printers and ink it is also necessary to note that some models offer a print mode NB quality, or printer can be modified with NB quality. It's a slightly different way of working which also results in very good qualities.
The Transparent : This is the medium that has most evolved in recent years that allows the evolution of printers and inks produce negatives of very good quality, comparable to the negative enlarged so silver. There are different type of transparency, some are still old building and do not support an over-inking and do not handle a slight inking too. Some of these anciennnes fabrications are still usable for processes that are not too defined as gum bichromate.
I will present only the media and opaque transprent very good qualities that offer better definitions and better management of the inking.
