How to create printed opaque acrylic charms using Paint Tool SAI

This tutorial contains everything you need to know about creating your own printed opaque charms including our white, black, coloured, metallic, frosted, glow in the dark and glitter acrylic charms, using the design software Paint Tool SAI.

Important - Colour Management

Please note that Paint Tool SAI can only create documents in RGB colour whereas we only print in CMYK colour.



A quick search on the internet for 'the difference between RGB and CMYK' will provide you with a wealth of information on this subject, but we wanted to make you aware that the colours of your designs on screen will be different to the colours of your final printed products.

The image below shows the RGB palette on the left and the same palette converted to CMYK on the right. RGB colours appear vivid with bright blues and greens. CMYK in comparison appear flatter with slightly duller colours.



We convert all Paint Tool SAI images from RGB to CMYK before printing so do remember to bear these colour differences in mind. Always remember to order samples if you require any colour accuracy or if youare unsure or feel that you may be unhappy with the results.

1. Download our templates

To start submitting your custom printed acrylic charm designs you'll need to download our design templates. Templates are available in various sizes ranging from 0.5" (12.7mm) right up to 3.5" (88.9mm).

Download our Paint Tool SAI templates >> here << and open your chosen size.



Each template comes with a working area where you will import or create your designs. Please make sure that your artwork fits INSIDE of the blue borders.

2. Understanding our layers

Opening the template, you will notice that there are 7 layers in your Layers palette.



IMPORTANT - Please don't rename existing layers or create additional layers as this will confuse our systems when processing your designs.

'OFFICE USE ONLY' Layer
This layer contains the blue borders which your design must sit inside, our logo and a brief description of the template size that you are using. DO NOT USE THIS LAYER.

'Artwork' Layer
This layer is where you should place your artwork. Please make sure that you choose the correct template size and that your artwork fits neatly inside the blue borders.

'White' Layer
Adding a base layer of white to your charms will make your colours crisper and more vivid. Use this layer to show us where you would like this layer of white to go.

'Gloss Varnish' Layer
If you would like your charms to have a gloss finish as opposed to a matte finish, you can use this layer to show us where you would like your areas of gloss to be placed.

Cut Area Layer
Use this layer to show us where you want your charms to be cut. We'll use this information to create a path which will then be used to create a cut line for our laser cutters.

Please note that we do not print right up to the edge on any of our acrylic charms. It is therefore ESSENTIAL that you create a border of AT LEAST 1mm between your artwork and your cutline. We can however print right up to the edge when printing onto wood as the print is more durable on this material.

Failure to leave a 1mm border on your acrylic charm designs can result in damage and lifting along the printed edge of your charms as a result of the heat generated by the laser. See step 5a for more info.


'Hole Template' Layer
Drag and drop the hole template onto your artwork to show us where you would like your hole to be placed. The dotted red line represents the recommended distance that your hole should be placed INSIDE of your design.



'Loop Template' Layer
Drag and drop our loop template onto your artwork to show us where you would like your loop to be placed. The light red, outer circle represents the loop size and the dark red inner circle represents the hole within the loop.



3. Importing your designs

Select the 'Artwork' layer in your layers palette and draw your design directly on this layer or, copy (CTRL+C) and paste (CTRL+V) previously saved artwork.

Please do not mirror or flip your artwork for any of our opaque charms.

4a. Adding a layer of white

To guarantee bright and crisp colours for your artwork, you will need to add a white base layer to your designs. This white layer will sit behind your artwork and will ensure that the colours of your charms are consistent, regardless of what material you choose.

Check out the charms below by jwhitneyart.com. Using a white base layer of ink means their designs look the same on our white and black acrylics.



Please note that we ask that you create this white layer for ALL of your charm designs, even white acrylic charms.

To create your white base layer simply hold down the 'CTRL' key and click on the thumbnail of your 'Artwork' layer. This will select all of the elements of your artwork layer.



You will now need to inset (shrink) your selection by 1 pixel to prevent any areas of white from showing around the edge of your charms once they've been printed.

To do this invert your selection SELECTION > INVERT, your selection should look like the image below...



With your selection inverted, use the increment option SELECTION > INCREMENT once to inset your selection. Now invert the selection again SELECTION > INVERT.

Click on the RGB slider in your colour & tool panel and create a Cyan colour (R:000 G:255 B:255)

Select the 'Bucket' tool and click inside your selection to fill the selection Cyan.

Click 'OK' and 'OK' again. You should now have a Cyan silhouette of your original artwork, placed on your 'White' layer.



Be aware that contracting your selection in this manner can have an effect on the pixels selected. Always zoom in on areas with fine details such as strands of hair or small point text and check that you are happy with the results.

Please remember that we always recommend ordering samples before committing to large print runs, so that you can check that you are happy with the result. mistakes can not be rectified once your charms have been printed.

5a. Working with gloss varnish

You can choose to have a gloss or matte finish on your designs by selecting the matte or gloss option when placing your orders. If you choose 'Gloss' as your option, you will need to create a grey silhouette on the 'Gloss Varnish' layer, similar to how you created the cyan silhouette on your 'White' layer in step 4a. of this tutorial.



Click on the RGB slider in the 'Color and Tool' panel and create a grey with the following colour values R:150 G:150 B:150.

CTRL click on your 'Artwork' layer to select all of the elements of that layer. Select your 'Gloss Varnish' layer and using the Bucket tool, click inside of your selection.

You should now have a grey silhouette of your original artwork, placed on the 'Gloss Varnish' layer.

5b. Spot gloss varnish

As well as being able to add gloss varnish to your entire design, you also have the option to limit this to certain areas, in effect highlighting particular elements of your design. Handy for creating textures like water droplets or snakeskin.



To do this, simply delete any unwanted parts of the grey silhouette that you created in step 5a. or create a custom silhouette based on the areas of your design that you would like to highlight.

6a. Adding a border / cut line - Important!

You can now decide on the thickness of your border, which will be used as a cut line. It is ESSENTIAL that you make this border AT LEAST 1mm wider than your artwork (unless you are printing onto wood, in this case your artwork can run to the edge of the charm). Failure to do so can cause your printed design to lift along the cut edge as a result of the heat generated by the laser. A 1mm border will prevent this from happening.

To create your cut line, CTRL click on your artwork layer to select all of the elements of that layer. Select your 'Cut Area' layer and use the Increment function approximately 20 times to increase your selection by the required amount.

A slightly quicker way to do this is by using the shortcut ALT+S followed immediately by the 1 key. Do this 20 times.



Using the Bucket fill the selection black. This colour will not be printed, it's simply for our designers to use as a guide when creating your cut line.



TIP - Use the Eraser tool to round off any square edges and the Brush tool to cover any areas missed by the 'fill' command.

6b. Adding a hole

Drag and drop the hole template into position on your design to show us where you would like a hole placing.



The solid inner circle represents the hole and the dotted outer circle represents the recommended distance that your hole should be placed INSIDE of your design.

Please don't merge the hole template with your design as we will need to remove this before printing so that it's not visible on your finished charms.

6c. Adding a loop

If you would prefer a loop instead of a hole drag and drop the loop template into position on your design to show us where you would like a loop placing.



The light red outer circle represents the loop size and the dark red inner circle represents the hole within the loop.

Please don't merge the loop template with your design as we’ll need to remove this before printing so that it's not visible on your finished charms.

7. Submission checklist

Congratulations, you've finished creating your custom charm designs! All you have to do now is check the following before submission...

  • Your white base layer is Cyan and located on the 'White' Layer (Step 4a.)
  • Your gloss varnish layer is Grey and located on the 'Gloss Varnish' layer (Step 5a.)
  • The hole and loop layers have NOT been grouped or merged with the rest of your design.
  • Your border is AT LEAST 1mm thick.
  • Your charm template contains 1 charm only. Additional charms will be sent separately.

8. Saving and submitting your designs

1. Submit your artwork immediately

If you have already created your designs, you can send them to us using the 'Upload Artwork' button, located on our product pages or by emailing them to ‘info@zapcreatives.com’.
