Arcdeco SO 110 Stoving Offset Ink for Food and General Line Sheet
A thermally cured lithographic ink series in process and spot colours for tinplate, tin-free steel and aluminium sheet, printed over a cured size coat or white base and stoved under a finishing varnish. It is formulated to trap wet on a multicolour press and to hold colour and adhesion through later bakes, body making and retort.

1. Product description
A thermally cured lithographic ink series, in process and spot colours, for printing over a cured size coat or white base on sheet that will be made into three-piece food, general line and aerosol bodies and ends. It is formulated to trap wet on a multicolour press, to hold its colour under a finishing varnish applied wet or over the stoved ink, and to keep adhesion through beading, flanging, double seaming and a retort cycle. Mis-specified, it shows as colour drift or loss of adhesion after a later bake, or as blush under the varnish after retort. It is qualified with Arccan SF 120 below it and Arccan SF 230 over it.
2. Features
- Traps wet on multicolour sheet-fed presses, with tack graded down the colour sequence; also runs on single-colour presses with a stoving between passes
- Holds colour under a finishing varnish applied wet or over the stoved ink
- Keeps adhesion through beading, flanging, double seaming and a retort cycle
- Qualified in the stack with Arccan SF 120 below it and Arccan SF 230 over it
3. Recommended uses
Printed decoration on sheet made into three-piece food cans, general line cans, aerosol bodies and ends. Sheet laid out for welded bodies keeps an unprinted margin at the weld.
Substrates. Tinplate, tin-free steel and aluminium sheet carrying a cured size coat or white base, typically Arccan SF 120. Sheet laid out for welded bodies keeps an unprinted margin at the weld.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Thermally cured lithographic paste ink, thermosetting resin vehicle in high-boiling ink oil | Formulation |
| Form and colour range | Paste ink in process and spot colours, matched to an approved standard | Visual |
| Composition | Thermosetting resin vehicle in high-boiling ink oil; formulated without PTFE wax | Supplier formulation record, declared not tested |
| Tack | Stated per colour on a named instrument, speed and roller temperature, set against the customer's press and graded down the colour sequence for wet trapping | ISO 12634, rotary tackmeter; readings compared only on the same instrument type, roller temperature and speed |
| Viscosity at 25 degrees C | 20 to 120 Pa.s, with yield value reported; stated per colour on the Certificate of Analysis | ISO 12644, falling rod viscometer |
| Fineness of grind | 5 micrometres or finer | ISO 1524 |
| Colour against the approved standard | ΔE00 1.0 to 2.0, agreed by colour and measured on the customer's own basecoat or metal | Measurement to ISO 13655, colour difference by CIEDE2000 to ISO/CIE 11664-6, against a signed standard on the production substrate |
| Colour and adhesion through later bakes | Colour shift within the agreed tolerance, typically ΔE00 1.0 to 2.0, and cross-cut 0 to 1, after one to three further bakes at the line's schedule | Printed panels over-baked in-house, measured to ISO 13655 and ISO/CIE 11664-6, adhesion to ISO 2409 |
| Retort resistance | No blush, blistering, colour change or loss of adhesion under the finishing varnish after steam retort, commonly 60 to 90 min at 121 degrees C, or the filler's own cycle | Customer or can-maker protocol on filled and processed packs, with cross-cut to ISO 2409 afterwards |
| Formability of the printed stack | No cracking or loss of adhesion at 6 to 9 mm cupping indentation or over the mandrel agreed for the gauge; confirmed on beaded, flanged and seamed bodies | ISO 1520 cupping, comparative on can stock; ISO 1519 or ISO 6860 mandrel bend; then the customer's own formed parts |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Wet offset with dampening on a sheet-fed press: colours trapped wet in the agreed sequence on a multicolour press, or printed and stoved one pass at a time on a single-colour press. |
| Surface preparation | Print over a cured size coat or white base, typically Arccan SF 120, clean and free of dust. Keep an unprinted margin at the weld on sheet laid out for welded bodies. |
| Press preparation | Supplied ready for press. Any adjustment of tack or flow is made only as advised for the grade and press, keeping tack graded down the colour sequence. |
| Dry ink film weight | About 0.5 to 2.0 g/m2 dry per colour, set by colour, coverage and press and confirmed at trial. |
| Stoving schedule | 10 to 12 min at 150 to 205 degrees C peak metal temperature in a wicket oven, set by the finishing varnish; ink-only passes at the lower end. Peak metal temperature is traced by thermocouple on a sample sheet. |
| Overcoat | Finishing varnish, typically Arccan SF 230, applied wet in-line and stoved with the ink, or applied on a separate pass over the stoved ink. |
| Qualification | A trial on the customer's line through every later bake, body making and retort is required before approval. |
Process. Wet offset with dampening on a single or multicolour sheet-fed press. The finishing varnish is applied wet over the ink in-line, with ink and varnish stoved together, or on a separate pass over the stoved ink, as with Arccan SF 230; each stoving is typically 10 to 12 min at 150 to 205 degrees C peak metal temperature in a wicket oven. A trial on the customer’s line through every later bake is required.
6. Storage and handling
Store in the original closed containers in a cool, dry place away from direct sun and sources of heat, and keep lids closed between uses to limit skinning. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
