What blends of batch 48 were tested, and how did they do?21 Aug 03:08
All six batch-48 records retrieved. The base batch plus five blend/variant sample records (48Q, 48K, 48BC, 48B99, 48PA50), each with NC-PU ink application-test rows. I have everything needed.
## Blends of batch 48 tested and their results
Five batch-48 derivative samples were application-tested in NC-PU ink (Violet 23 and Black), each benchmarked against a same-day BYK-9076 standard run. (The base "Batch 48" record is a synthetic lab batch — Vicaspin LUB 1010 phosphate ester + Epomine SP-018/2-ethyl hexyl acrylate intermediate — not itself a tested ink blend.)
48Q (trial 05.11.2025) — Violet 23 only: Viscosity 30 sec, Gloss 60.3, Colour Strength 98–99.00%, Resolubility 5, Opaque, vs same-day standard (Viscosity 29 sec, Gloss 62.9, Colour Strength 1, Resolubility 4). Gloss lower than that day's standard; resolubility rated one better. No Black row recorded for 48Q.
48BC (trial 28.11.2025) — Violet 23: Viscosity 36 sec, Gloss 63, Colour Strength 97–98.00%, Resolubility 3, Opaque, vs standard (28 sec, Gloss 72, Resolubility 4) → gloss inferior vs that day's standard. Black: Viscosity 36 sc, Gloss 34.9, Colour Strength 1, Resolubility 4, Eq to Std, vs standard (35 sec, Gloss 33.5, Resolubility 4) → gloss marginally better, otherwise equivalent.
48B99 (trial 28.11.2025) — Violet 23: Viscosity 37 sec, Gloss 61.9, Colour Strength 97–98.00%, Resolubility 3, Opaque, vs standard (28 sec, Gloss 72, Resolubility 4) → gloss inferior. Black: Viscosity 38 sec, Gloss 30.2, Colour Strength 98–99.00%, Resolubility 4, Eq to Std, vs standard (35 sec, Gloss 33.5, Resolubility 4) → gloss slightly below, transparency eq.
48K (trial 05.12.2025) — Violet 23: Viscosity 38 sec, Gloss 59, Colour Strength 95–96.00%, Resolubility 3, Opaque, vs standard (35 sec, Gloss 70.6, Resolubility 4) → gloss inferior, colour strength below the 97+ seen elsewhere. Black: Viscosity 39 sec, Gloss 30.4, Colour Strength 98–99.00%, Resolubility 3, Eq to Std, vs standard (36 sec, Gloss 35.3, Resolubility 4) → gloss and resolubility below.
48PA50 (trial 12.12.2025) — Violet 23: Viscosity 32 sec, Gloss 63.3, Colour Strength 98–99.00%, Resolubility 4, Opaque, vs standard (27 sec, Gloss 73.2, Resolubility 4) → best violet of the group, gloss still below same-day standard, but resolubility matches standard. Black: Viscosity 46 sec, Gloss 45, Colour Strength 1, Resolubility 4, Eq to Std, vs standard (44 sec, Gloss 44.9, Resolubility 4) → essentially equivalent to that day's standard.
GAP: no explicit verdict field is populated in any of these rows (verdict=null), so "inferior/equivalent" above is my comparison of the recorded numbers to the recorded same-day standard, not a stored judgment. Only these rows exist in this drop — absence of a failure report does not mean the others passed.
