Thanks for your follow-up. I am excited to integrate the Piezography inks into my alt workflow, especially the photogravure side of the equation. As you are aware true photogravure (resist on copper) is a fairly “organic” process in respect to all the many variables including environmental conditions. Those variables include:
- Carbon tissue sensitization
- Creation of positive
- Exposure of positive to carbon tissue/resist
- Proper resist lay down on the plate
- Resist drying and humidification
- Plate Etch
- Inking along with type of ink
- Paper choice
In short quite a few variables to nail down into a consistently objective workflow and more aptly described as controlled subjectivity/chaos. Unfortunately I do not have a “standard” workflow currently as my work in the process, while relatively successful over that last bunch of years, is in “fits and starts” often followed by long periods of inactivity. The process is dependent on a serious time commitment.
My current situation is one that I am not going to be using Cape Fear Press’s Phoenix Carbon Tissue (that I used previously) and will not be starting all over with their Dragon Carbon Tissue and the Piezography Inks for the positive creation. I am actually starting all over with a whole new workflow that will hopefully yield more consistent results. My first step in the journey is to find out what the best exposure for the Dragon Tissue will be. As I pursue this I would like to work on the Positives using the Piezography inks. Yes I am a masochist, but I know in the end the unlimited creative reward will be remarkable.
As I move along on this is there a particular curve that is a better starting point than another? I am new to all the Piezography forums and support and really do not know what is what and where to access the needed resources. I guess there is a big differentiation between Piezography and PiezeDN and I get that. Photogravure crosses the lines. Once I am able to get the good exposure and density for the Dragon Tissue I will be able to provide densities.
I thank you for your willingness to support and help creating a limited “pre-linearized” pos curve. I am sure this will be a useful piece of data for working with other customers with similar issues. It may be a while before I have the information for you. This is for my personal work and fulltime jobs and lie issues get in the way. I am fortunate however, as I personally own a reflection/transmission Eseco TRC-60 P equipped with AA filers, and X-Rite i1Pro Photo and a UV sensitive X-Rite 361T.
So there are two questions I have at the moment:
Given my back-story is there a preferred Piezography curve I should use since I am really starting from scratch. Where are these curves located, it gets a bit confusing when working between DN and Piezography resources.
On step 6 of your recent email, I suspect you are looking for the transmission density of the last step on the positive and not the related reelection reading from the print?
I am very glad I chose to move into the Piezography/PiezoDN ink system and appreciative of you willingness to support.
