Printing Your Logo on Kraft

Why does brown card change the way your logo looks?

Kraft is brown, and that brown sits underneath every ink you print. Ink on card is mostly see-through, so the board colour mixes into yours. A soft pink turns dusty. A pale blue drifts towards grey-green. Anything light loses its edge and starts to look like part of the card.

Dark inks do the opposite. Black, deep green, navy and dark brown cover the board rather than fight it. Your screen also shows a bright white background, so a file always looks livelier on your laptop than it does on the finished box. Judge your colours against a brown paper bag, not a white page.

Which colours hold up best on kraft?

Think of kraft as a mid-tone background. Colours with plenty of contrast against mid-brown read clearly, and colours close to brown vanish. The table sets out what usually happens on a one or two ink job.

Two ink colours is plenty. A dark main colour for the logo plus one accent for the scent name keeps the box looking deliberate rather than busy.

When should you add a white ink panel?

A white ink panel is a block of white printed onto the kraft first, with your design printed on top. It gives pale and bright colours a clean base, so a lavender logo actually looks lavender.

Use one when your brand colours are light, when you want a coloured illustration, or when a fine pattern would otherwise sink into the grain. Skip it when your logo is a single dark colour. Bare kraft with black ink often looks better than a panel.

The trade-off is the look. A panel reads like a label, which suits a neat centred badge on the lid or front. A panel covering the whole face turns the box into a white box with brown edges. Many makers keep the panel about 60 x 40 mm on a 90 x 60 x 25 mm bar box and leave the rest bare. To compare shapes first, browse our kraft soap boxes.

How big should the logo be on a soap box?

Work from the bar, then the box. The box inside is the bar plus about 2 mm each way, so a 90 x 60 x 25 mm bar of about 100 g sits in a box measuring roughly 92 x 62 x 27 mm inside. Those are the faces you are filling.

• 90 x 60 x 25 mm (about 100 g): a lid face near 92 x 62 mm takes a logo around 45 to 55 mm wide.
• 75 x 50 x 25 mm (about 60 g guest bar): a face near 77 x 52 mm suits a logo about 35 to 45 mm wide.
• 100 x 65 x 30 mm (about 150 g): the larger face carries a logo up to 60 mm wide with space around it.
• 70 x 50 x 20 mm (about 50 g): the small face wants a simple mark, about 30 to 40 mm wide.
• 85 x 60 x 30 mm (about 110 g): a near-square end suits a stacked logo about 40 mm wide.

These are starting points, not rules. Leave at least 5 mm clear of every fold and edge, so a slightly off cut never clips your name.

How do you prepare the file?

Good files are simple files. Work through these steps before you send anything, or begin in Design Your Soap Box if you would rather start from a layout.

1. Save your logo as vector artwork, such as a PDF or SVG, so edges stay crisp at any size.
2. Convert all lettering to outlines, so a missing font cannot swap your typeface.
3. Keep each ink on its own layer as flat colour, not a flattened photograph.
4. Make lines and strokes at least 0.3 mm thick, because hairlines break up on the grain.
5. Add a 3 mm bleed to artwork that runs to the edge, and keep key content 5 mm inside the folds.
6. Send the file with your bar size and ink choice, then check the free design proof before you approve it.

What about small text and ingredients?

Kraft grain breaks up small type. Keep body text above about 7 pt, choose a clean sans serif, and print it in your darkest ink. Thin serif lettering and white text at tiny sizes are the first things to fill in or fade.

Soap sold in the UK usually carries the product name, weight, ingredients and the maker's details, and cosmetic rules apply, so check the current UK cosmetics rules before you finalise the layout. If your ingredients list is long, move it to a separate paper label on the back and let the box carry the logo alone.

Can you add foil, embossing or spot varnish?

Six finishes can go over a kraft logo, each priced on your quote: embossing, spot varnish, foil, soft-touch, gloss and matt. On kraft they behave differently from white card.

Embossing needs no ink at all, and a pressed logo on bare brown board looks properly handmade. Foil works over a dark base or as a small mark on its own, though it shines against a matt board. Spot varnish adds a faint sheen over part of a printed logo. Soft-touch feels lovely but can scuff when boxes rub together in a parcel. Tell us the effect you want and we will suggest what suits your bar, whether you are ordering custom printed soap boxes or something simpler.

Will a sweating bar or fragrance oil mark the print?

Card can mark if a bar is still sweating, and strongly scented oils can bleed into kraft over time. Let cold process bars cure fully before boxing. Give melt and pour a day or two to settle, so no glycerine dew forms on the surface.

A window patch with clear film keeps fingers off the bar, but film is not a seal, so do not rely on it for moisture. Read window patches and moisture for the full picture. Keep logo ink at least 5 mm from the window edge, so the cut line never touches your lettering.

Four mistakes soap makers make with kraft artwork

Most reprint stories start with the same few slips. Pale logos are the biggest. A cream wordmark that looked elegant on screen disappears on brown. Second comes the photograph, which turns muddy on kraft grain, so use flat illustration or type instead. Third is a logo set right up to the edge, where a 1 mm cutting shift trims a letter. Fourth is too many inks, since a third and fourth colour fight the board rather than help it.

A quick test costs nothing. Print your artwork on plain white paper, lay it on a brown paper bag and squint. Whatever fades is what the box will lose.

What happens between proof and delivery?

Send your bar size and logo, and every order is quoted by email within one working day. Prices start from £0.25 a box, with finishes and sizes priced on the job. You then get a free design proof before anything is printed, so you can check placement, spelling and colour direction on kraft.

Production takes 4 to 6 working days after proof approval. Delivery is free, tracked and takes 2 to 3 working days to the UK mainland. Misprints or damage reported within 10 days are reprinted or refunded. Ready to begin? Ask for a quote today.
