Lino Etching

I have seen lovely textured and atmospheric prints made with the lino etching technique. When I tried this some time ago nothing happened – it was a total non event. I don’t like being defeated and I was keen to find out just what I’d done wrong.

I am a member of Inkers Printmakers, this gang of Yorkshire based printmakers exhibit as a group as well as getting away from it all once a year to spend time together. In April twelve of us set off for Barmoor at Hutton-le-Hole for a long weekend of sketching, walking, eating and printmaking. Our annual weekend away usually includes someone sharing a printmaking technique – this year Jenny demonstrated lino etching so here was my chance to discover how to do it properly.

Being rather impatient I struggle with the length of time it takes to cut detailed lino plates. Lino etching on the other hand, is relatively quick. You discover unpredictable lines and textures that are very exciting. The effect doesn’t resemble traditionally cut lino but you can add cut marks to the etched plates.

An added bonus is that anyone who suffers from arthritis or weak hands and wrists may find lino cutting too painful to enjoy. Lino etching does not tire out those muscles as you get the results by using various liquids rather than cutting tools.

What is Lino Etching?

A caustic soda solution is painted onto lino – this eats away the surface creating interesting textures that often print in unexpected ways.

You can control the process by masking off areas of the plate to prevent or reduce the effects of the caustic soda etch.


Here is how we did it at Barmoor

Caustic soda decomposes proteins. Proteins are things that are (or have been) alive – for example plant and animal tissues, so natural oils and fats, hair, and skin. This also includes you! If you get it on your skin it will cause painful chemical burns.

It does not affect synthetic man made materials (but can affect aluminium,) so use plastic containers to mix it in, rubber gloves and plastic aprons, tablecloths etc.

Please see the ‘caustic soda’ post for more essential information about this chemical.


Recipe for caustic soda lino etching solution

200 ml water

3 tbsp caustic soda

2.5 tbsp wallpaper paste

Put the water in your pot first, then slowly add the caustic soda, stir until it dissolves. Be aware that it gets hot and gives off fumes at this stage.

Sprinkle the wallpaper paste on and stir this till it is thick and even.

The mixture we used was like thick jelly – you could drop a blob a centimetre thick on to the lino and it would just sit there etching away.

If your mixture is too runny it will flow off the lino or dry out before etching it.

(Making the mix too thin was my original mistake).



Traditional lino is made from linseed oil and chalk – linseed oil is a natural protein so the caustic soda will dissolve it.

Caustic soda etching will not work on vinyl based ‘soft cut’ lino as this is synthetic and doesn’t contain proteins.

You can simply apply the caustic solution to the blank lino plate. Coarse synthetic brushes (not hogshair as that will dissolve in the solution) make nice sweeping strokes. You can drop it on in blobs to etch random shapes. Also try scraping it with a plastic comb to make lines in it.

As it starts working you will see the colour of the lino change to a darker shade of brown.



The longer you leave it the deeper it will etch. It is good to start with some timed test pieces; 10 minutes will be fairly shallow, leave it for an hour and it will have bitten much deeper. You can create different levels of etch on a lino plate by adding more caustic solution part way through the etching process.


Masking areas of the lino plate

To make more controlled designs you can mask areas of the lino plate to prevent the etching solution reaching it. As caustic soda dissolves natural materials you must use man made materials as a mask.

It takes a while to get the idea that the areas you mask will print black, etched areas will be white. This is the reverse of conventional etching – it all helps to keep your brain agile!



Electrical tape worked well, making sharp edges and geometrical shapes. I guess other plastic tapes or stickers would also work well.


Petroleum jelly

Vaseline (petroleum jelly) was excellent – smear it on, wipe off areas, scratch or comb into it to get different marks. If the Vaseline is thin the etch may start to bite through it at the edges giving lovely textures.


Paraffin wax

We melted the wax and used tjantings to draw loose flowing lines on the plate as you would in batik. The layer of wax can be scratched into with a needle or drypoint tool – fine lines will etch where the wax is removed


Stop out varnish

This is a spirit based bitumen varnish used in traditional etching. Put it on thick and the etch will not penetrate it, if it is thinner interesting lacy patterns form as the caustic soda bites through it.

There are surely lots of other materials you could try – I wondered about nail varnish? Leave a comment below to let me know if you come up with any others that work well for you.


Cleaning the plate

Once you have masked the plate and etched it as long / deep as you want all the caustic soda and masking materials must be removed.

Wearing gloves, scrub it with a stiff nail brush under running water. Keep scrubbing till the brown colour is gone. It is fine to put caustic soda down the sink as it is designed for clearing drains.

We used malt vinegar after washing to finally neutralise the alkali but not everyone does this.


Remove any wax left on the plate by laying a sheet of newsprint over the lino and ironing it several times. Other masking materials may need solvents like meths to remove them if they are still clinging on after the caustic soda has done its work.

The etched plates look exciting and are lovely objects in themselves. Enjoy feeling your plate before you print it!


Printing the etched lino

Once the plate is dry take a simple relief print to see what has happened – you will no doubt get some nice surprises.

If you don’t have a press lay your paper on the plate, cover it with grease proof paper and rub the back evenly all over with a wooden spoon.

After your test print you might decide to carve more details into the plate, or etch some more areas.

I find the plates work well inked up as intaglio and then rolled over with a different colour as a relief print. As the plates have several distinct layers it is also interesting to try viscosity printing with them.

If you need more hands on instruction Jenny has a studio at West Yorkshire Print Workshop and sometimes runs lino etching courses there.

Have a look at my post about other artists who use this technique for more inspiration….

    As oven cleaner is based on caustic soda I have been trying the strongest I could find, having spent a couple of days on a course. I bought 12 A5 pieces of lino and just a play. I need to print them properly.It works and perhaps is not as vicious as the ‘real stuff’ It is the thickness of the wallpaper caustic soda we used on the course. Being dispensed in a plastic bottle which was was to close, I was able to make up plates on per session without any mess, also it is not as vicious on your hands. Have several successful plates, leaving them over night before rinsing, Having no vaseline I found I had some emollient cream and the surface is intriguing. Some of my original dribbles are a bit harsh so I intend to go back over them with vaseline. Drain cleaner, which is also made of caustic soda was a total failure! Too weak? One of the things I want to try is printing one of my plates with an oil based ink, and see how it works using this for a dry point etching.. certainly an enjoyable area for experiment, and using the oven cleaner cut out all the mixing,

      Thanks Cathy – that is very interesting. It is always good to hear tips which make things easier. I am surprised drain cleaner didn’t work as I thought that was basically caustic soda.
      Have you put any of your prints on instagram / facebook etc? It would be good to see them.

    Hello Emily,

    Thanks for the link to my blog post. I wish I had had access to your experiments before I tried mine! I love the idea of using vaseline as a resist, and will definitely try it out.

    Best wishes,

    Philip Hartigan

      Hi I am glad you found something to add to your repertoire – if you have a spare 5 minutes you can amuse your friends and family by doing a face print using vaseline too!

      Hello, have you tried Marmoleum for this technique? This is what I have on hand and will give it a go. Here in Canada the Lino used for craft is so expensive. I must say a very clear instruction article with lots of creative options. I appreciate this.

      1. Emily Harvey Post author

        I think marmoleum would work well – as long as it is made from linseed oil as the caustic soda will dissolve fats and oil so it will etch it. Just make sure you aren’t using synthetic material which the caustic soda won’t work on.

    Hi Emily

    Glad to hear you’ve had some successful results with lino etching – it can become quite addictive ! I usually use stopout as a resist, sometimes candle wax. I did try wax crayon on a course but it didn’t really work. Often, I don’t use a resist at all, just work directly onto the lino with the etch solution.

    I haven’t tried using intaglio inking and rollers, usually just use different soft and hard rollers, so will give that a try.

    Some lovely examples that you’ve chosen. I found these sites helpful too when I was getting started:
