The task for this exercise was to cover card with Polyfilla and while it was still moist use mark-making tools to create textures. The dried block can be used multiple times.
I used a different brand product, but the same idea of a pre-mixed plaster, with an A4 piece of mountboard as the base. A lot of time was spent with a wallpaper smoother and the smaller tool provided by the manufacturer, trying to get a smooth and even layer of filler on the card. I wasn’t entirely satisfied with the result, but felt the need to move on before the plaster set too much. Next I used a variety of tools and materials to make marks, naturally basing much of my choice on materials used in previous assignments.

Bottom row: marks made with the side and ends of pop sticks; pressing and lifting a small triangular headed palette knife (similar to that used in print p4-16); plastic bath mat; heat gun treated plastic; plastic netting.
Areas were divided using a range of different strings, twine and braid. Working when the plaster is at just the right stage of setting is critical, and I would need more experience to get it right. Most I did too soon. Instead of leaving a clear mark the palette knife just squelched around – I suspect a matter of surface tension. I was able to lift corners of the hessian etc and check they came away clear before removing entirely. I left the heat treated plastic longest of all, but eventually was going away for a few hours and chose to risk taking it up too soon rather than risk the plastic setting in the plaster.
Drying was slow. Temperature was mid-20s celcius, humidity mid 50s when I was working on it, the next day was almost 30 degrees, and it still took over 24 hours to dry. The board had curved and there were more high and low points than I wanted. I brushed the plate to remove stray loose bits then set to work.

The plate was rolled with akua crimson red intaglio ink. Given the uneveness of the surface it was difficult to get ink on the plate. I rotated the plate and rolled from all directions.
The print was taken on cartridge paper. I started using my hand and a baren, but peeking showed that very little colour transferred. Wooden clay shaping tools were then used to press into small, detailed areas.

None of the dividing lines gave any detail.
Print p4-106
There were a number of areas with light coverage in the previous print. I wanted to get more colour, so applied the same ink with a dabber, trying to work into the crevices of the plate.
The printing method was the same as that used in p4-105.

Print p4-106
I wondered if the plaster was absorbing ink.
Print p4-107
I was even more determined to get a more complete print.
Akua diarylide yellow liquid pigment was applied using a smallish bristle paint brush across the plate including all the crevices. I wiped the yellow off the high surfaces with telephone book paper, then rolled akua crimson red intaglio ink over the plate.
The print was taken on very slightly damp Arches 88 paper. Using the wooden shaping tools I worked for a long time, trying to press the paper deep into every part of the plate.

Print p4-107
It still wasn’t the coverage I wanted. Possibly a printing press and slightly damper paper might have got a better result.

Next I rolled phthalo blue liquid pigment on the gelatin plate. I pressed the plaster plate onto the gelatin, working my way across the surface and then rocking back and forward slightly – most but not all of the bend in the plaster board had worked out in previous prints.
The print was taken on cartridge paper.

The blurring is most pronounced in the upper right area where the notched adhesive spreader was used. A visual depth and vibration has resulted which is quite striking. I like the contrast of the evenly spaced zig-zags blending into shimmering tentacles. There is less dramatic interest in the other textured areas, although once again I see promise for the right application.
The plaster hadn’t been cleaned before this use, and traces of previous red have printed. I wondered if there would be substantial amounts of the old colour and some colour mixing, but there is not enough for major impact.

I repeated the previous method, with less forceful pressing of the plaster collage plate. The print was again taken on cartridge paper.

The detail of the print is sharp and clear and very interesting. In the gelatin prints of collage plate 1, such as print p4-97 (14-Dec-2015) the precision and detail of the print was almost too much for my taste. The boundaries were crisp, not hesitant or provisional. There was a flatness and uniformity.
In the current print there is great variation in value, there is a lot of movement and the marks seem more assertive, more individual. I look at the results and see more than just suitability if the right need comes up. The marks excite me, make me want to use them, to explore further. The roughness of the plaster and the smooth reflection of the gelatin has combined to open new possibilities.
Print p4-110
The plaster collage plate by this time was dense with colour. I printed it onto cartridge paper without the heavy working with the wooden shapers used in the earlier prints.

Print p4-110
I am very interested by all the variations in printing that one plate can provide.

I rolled akua crimson red intaglio ink on the pvc plate. The print was taken on cartridge paper user a brayer.

The same ink and inking method was used. I again printed on cartridge paper, but this time through the ezicut press.

I next tried an intaglio print. The red ink was pressed across the surface and into all depressions. The surface was then wiped with phone book paper.
The print was taken on damp Arches 88 paper using the ezicut press.

The print itself is not exciting, but I am pleased to have the option of creating embossed pvc plates and printing in this style. I think the material and technique is worth developing in the future.
Print p4-114
The gelatin plate was once more rolled with phthalo blue liquid pigment. The pvc plate was pressed into the ink and removed. The print was taken on cartridge paper.

The gelatin plate picked up what detail there is, but the flaws (clumps in the original mixing of the gelatin) are becoming more pronounced.

The final print is a ghost on cartridge paper.

I’ve built up a good range of materials and techniques. In the next exercise, the last for this assignment, I need to bring things together and put my new skills to use.
