Every tech pack lives inside a style. A style is a folder for one product — it holds your mockups, sketches, and the tech pack together. There is one active tech pack per style.
Anyone can make tech packs. The Free plan allows 3 active tech packs and Creator allows 5. On the Free plan, copies and versions of a style count once and packs you have unlocked do not count; if you reach the limit, delete the tech packs for a style you no longer need, or upgrade. On Creator, delete a pack you no longer need or upgrade. On the Free plan the preview shows every page with a watermark; unlock a pack for £15 to download it, or choose a paid plan for every export.
Brands are optional labels to organise styles (for example by label or customer). Manage them in Settings → Brands. To put your logo and brand colours on the exported PDF: link a brand to the style, turn on "Brand branding on PDFs" in Pack settings, and turn on "Custom branding on tech pack PDFs" for that brand. Choose Light paper for a light factory document, or Bold fill to colour the cover and headers.
A logo on the PDF is included on every paid plan — personal (Creator, Master, Expert) and team (Duo, Studio, Maison) — and on any tech pack you unlock on the Free plan.
Open + Create → Tech Pack, or start from a style, mockup, or sketch. It is one screen: pick the style the pack is for, or start a new one from a photo, a sketch, or a written description.
Every pack lives inside a style, but you do not have to make one first — naming the product and picking its type on the create screen creates the style for you. Pack name, status, and size scale sit under Tech pack details — choose Change if you want to set them up front; you can change all of them later.
Press Create. If that style already has a tech pack, you are sent to the existing pack. One style keeps one active pack; use colourways for extra colours rather than creating a second pack. A blank pack then offers Draft this tech pack with Auto-Complete — it does not start on its own. If you added photos but no sketch, you can draw front and back sketches for How to Measure before the draft. That drawing uses tokens. Auto-Complete does not. The cost is under Auto-Complete.
A tech pack can be for an accessory as well as a garment. On the create screen, pick a product type under Accessories: Scarf, Hat, Belt, Socks, Gloves, or Bag.
The size chart, How to Measure points, and construction headings follow that product. A bag uses width, height, gusset, and strap. You use the same editor and Auto-Complete as for a garment: attach a mockup or flat sketch, review the draft, then export the PDF.
The editor has six steps: Product visuals, Materials & colours, Size chart, How to measure, Bill of materials and Construction notes.
Move between steps with the tabs or Next. The switch in the top bar shows the form only (Edit), the form beside the live PDF preview (Split), or the PDF on its own (Preview). You can type every section by hand, or run Auto-Complete to draft several at once.
Product visuals always stays. Turn other steps on or off in Pack settings if your factory does not need them.
Your edits save themselves. The bar shows Draft saved. Create revision is a separate button: use it when you send a pack to the factory, so you can restore that copy later.
Auto-Complete is at the top right of the editor. It opens a picker: tick the sections to draft. Empty and partly filled sections start ticked. Finished sections start unticked, so you do not overwrite work by accident.
From your mockup and sketch, Auto-Complete drafts materials and colours, the size chart, BOM, and construction notes. It also draws the How to Measure guide on the garment outline, and places numbered callouts on your sketch. You review and accept before anything is written, then the whole pack opens in Preview.
For best results, link a photoreal mockup and attach a flat sketch (a simple line drawing of the garment, sometimes called a CAD). Photos-only packs can still run, with a warning. If the pack has photos only, you can draw front and back sketches for How to Measure (1 token per flat, up to 2). That is a sketch generation, not Auto-Complete. Auto-Complete is included on paid plans; on the Free plan your first run is free, then each run uses 3 tokens. The Assistant can start a run if you ask; asking it to review a pack does not start Auto-Complete.
Open Pack settings from the top bar of the editor (on a smaller screen it is in the More menu). On a wide screen it takes the place of the form, with the live PDF beside it so you see each change as you make it; on a smaller screen it opens as a pop-up. Completeness shows which steps still need work. Under PDF pages, the toggles decide whether a section appears in the editor and in the PDF you download. Turn off sections your factory does not need — shorter documents are easier to read.
You can turn Materials, Size Chart, How to Measure, BOM, and Construction on or off. Visuals always stays. Revision history can include named revisions in the PDF. Use the up and down arrows under PDF pages to change the order pages print in. If the style has a brand, the pack follows that brand’s page order until you change it here; Reset to brand order puts it back. Logo and brand colours sit under Branding, and the style’s brand under Style & brand.
If something you typed is missing from the PDF, check that section’s toggle is on in Pack settings. Your edits are already saved. Page through the live preview to check it; it opens on the step you are editing.
Tech pack AI works best with a linked photoreal mockup plus a flat sketch (a technical line drawing). clothink can often use the flat stored on the mockup, files you add under Product visuals, or a sketch from your library.
You may not need a separate upload if the mockup already includes clear flat artwork — but a dedicated flat sketch usually improves measurements, How to Measure lines, construction detail, and sketch callouts.
Auto-Complete stays greyed out when there is no mockup, sketch, or photo. Add one under Product visuals. Turning a section off in Pack settings hides that step. It does not grey the button. Add numbered callouts on any visual yourself, or let Auto-Complete place them on the sketch for you to accept. Construction close-ups stay in their own grid (DETAIL A, B, C).
Upload fold diagrams under Product visuals → Sketches, and packaging photos under Product visuals → Construction details. How the garment is folded and bagged belongs in construction notes → Packing & folding, not in the BOM.
Start with Product visuals — attach a flat sketch and link a mockup. Auto-Complete reads these before it drafts anything else.
Then materials and colours, size chart, How to Measure, BOM, and construction notes. Auto-Complete can fill the empty ones in that order in one run. Size chart usually pulls How to Measure with it. Callouts on the sketch follow construction notes.
You can also type any step by hand. On an empty bill of materials or empty construction notes, Start with skeleton adds empty headings so you can fill them in yourself. Always check AI output in the live preview before sending to a factory.
The BOM (bill of materials) lists trims, labels, thread, hardware, and packaging needed to make the garment. Fabrics stay in Materials & colours and stay in sync with the BOM. Add rows yourself, pull from your material library, or tick BOM in the Auto-Complete picker.
If materials and colours are filled first, Auto-Complete can use those fabric rows instead of guessing. Construction notes then reference the materials you listed rather than repeating measurements.
Keep items you use often in the material library. When you change a library item that tech packs use, clothink asks whether to update those tech packs. Choose Update to copy the change into them; choose Dismiss and they keep what they had.
Colourways let you document several colour options for the same product without copying the whole pack — same structure, different colours, and an optional mockup per colourway.
Size chart Auto-Complete uses measurement points for your product type — a coat needs different points from a T-shirt. It combines those points with your sketch and mockup for proportions.
Link a size scale from your library to keep size names and grading steps consistent across tech packs. After the size chart, How to Measure draws a line on the outline for each point.
If measurement points look wrong, check the product type on the tech pack matches the garment.
Always check critical measurements against a physical sample or your block pattern. AI is a starting point. You sign off before anything goes to a factory.
The measurement guide (How to Measure) draws a line on the garment outline for every point on the size chart, so the factory sees where each measurement is taken.
Auto-Complete draws those lines for you. Ticking the size chart usually includes How to Measure as well. You can drag the lines afterwards, or tick How to Measure on its own in the picker to place them again. On a curved line, drag the letter to reshape the curve.
You need a size chart and an outline — a saved How to Measure outline, or a flat sketch Auto-Complete can pick. If the pack has photos only, you can draw front and back sketches first. That drawing uses tokens. See Auto-Complete for the cost. Edit anything that looks off before you export.
Materials & colours covers fabric composition, weight, finish, and colour names. These rows feed the BOM and construction notes when you run Auto-Complete.
Construction notes are grouped by garment area (for example collar and lining for a coat), with stitch, seam, and finishing detail. Numbered callouts on the sketch mark where. Construction notes explain how. Empty construction notes can use Start with skeleton, which adds empty headings so you can write in them.
Packing instructions live under Packing & folding — how the garment is folded, bagged, and boxed. If a fold diagram helps, upload it under Product visuals → Sketches.
Review every generated section before you sign off. Use terms your factory expects, and include fibre content, care labels, and country of origin where you need them.
The first pages show your mockups and sketches so the factory sees the product immediately. Two sketches sit on one page with the numbered list underneath when the notes fit. A long list on one sketch sits beside that drawing.
Construction close-ups are grouped and labelled DETAIL A, B, C. Numbered callouts sit under that grid when they fit.
The live preview shows the whole PDF and opens on the step you are editing. Confirm toggles, attachments, How to Measure lines, and callouts look correct before you download.
A brand can remember the house format for every new tech pack: page order, cover, which sections start on, and the bill of materials columns. The measurements, materials and notes stay on each pack.
Open Pack settings → PDF pages and choose Save as brand default. New packs for that brand start with those settings. A pack that already has its own page order keeps it until you reset it.
There is one active tech pack per style. Duplicate makes a copy without replacing the pack already on the style. For another colour on the same style, add a colourway instead of duplicating the whole pack.
Your edits save themselves. The bar shows Draft saved. Press Create revision when you send a pack to the factory, so you can restore that copy later.
Preview the PDF before every export: choose Preview in the top bar and page through it.
To send a pack to a factory or buyer, download the PDF or Excel and send the file.
Auto-Complete is greyed out — there is no mockup, sketch, or photo yet. Add one under Product visuals. A finished pack still opens the picker: tick the sections you want to redo. If a step is missing from the editor, open Pack settings. That section may be turned off. Turning a section off does not grey the button. Auto-Complete is included on paid plans; on the Free plan your first run is free, then each run uses 3 tokens.
A section is missing from the PDF — Open Pack settings → PDF pages and confirm that section’s toggle is on. Make sure the step has content. Your edits are already saved. Check the whole document in the live preview.
Logo or brand colours missing from the PDF — Check three things: "Brand branding on PDFs" is on in Pack settings; "Custom branding on tech pack PDFs" is on for the brand; and you are on a paid plan or have unlocked this pack (Free plan downloads need an unlock). The editor shows a warning if something is missing.
PDF images look soft — The on-screen preview is fitted to the panel, so it can look softer than the file you download. Download the PDF to check print quality. If it is still soft, upload the source image again at a higher resolution and export again.
Auto-Complete needs a mockup or a flat sketch it can read. If results are weak, add a clearer flat sketch. The button is greyed out when there is no mockup, sketch, or photo. A finished pack still opens the picker — tick the sections you want to redo. If a whole step is missing from the editor, open Pack settings. That section may be turned off. Turning a section off does not grey the button. Auto-Complete is included on paid plans; on the Free plan your first run is free, then each run uses 3 tokens.
Every tech pack belongs to a style, but you do not have to make one first. On the create screen, naming the product and picking its type creates the style for you. From a sketch or mockup, tap Create tech pack — if the product type is already known, the pack opens in the editor; otherwise you finish the create screen. One style keeps one active pack.
Link a brand to the style, then open Pack settings → PDF pages and choose Save as brand default. That stores the page order, cover, which sections start on, and the bill of materials columns. New packs for that brand start with those settings. To copy the measurements and materials themselves, duplicate the tech pack.
Open Pack settings → PDF pages and confirm the section toggle is on. Make sure the step has content in the editor. Your edits save themselves (the bar shows Draft saved). Then check the live preview: choose Preview in the top bar and page through the whole document.
Yes. You can type measurements, materials, and notes yourself. AI is optional. You are always responsible for checking accuracy before production.
