Name: Nick Osetek & Tessa Chambers Date: 5/31/2018
Room Temperature: 76*F Humidity etc: Dry
Experiment Title: Large 3 & 5-minute Plates
Experiment Goal: To see the distribution of tone on a large plane. Will the tone be more or less consistent in tone compared to our smaller 3×3 inch plates.
Plate material: Aluminum 5052
Plate Preparation: Degreased with Bon Ami and soy sauce, backed with contact paper.
Evaluation of Plate Preparation: Normal (Not steel wooled)
Etching Bath Notes: At this point the bath is still etching normally, still greenish and murky.
Time in bath: 3 min, 5 min
After Bath Evaluation: Plates had some spots from possible grease after etching, bath was murkier due to copper residue.
Removal of Grounds: N/A
Inking Methods: Bone black, 10% Burnt Plate Oil 00
Paper Type: Hahnemuhle Copperplate
Soaking Time: 30 min – 1 hour
Press, blanket set up, pressure: Praga press, 2 catchers, 1/8, 1/8
Conclusions: Our prints were fairly consistent with our past smaller 3×3 inch plates, even though these were larger planes. Our 3-minute plate was a tad lighter and spottier compared to our 5-minute plate which printed a much more solid black tone.
