How to create holographic acrylic charms using Paint Tool SAI

This tutorial contains everything you need to know about creating your own printed holographic 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 you are unsure or feel that you may be unhappy with these colour changes.

1. Download our templates

To start submitting your custom printed holographic acrylic charm designs you’ll need to download our design templates. Templates are available in various sizes ranging from 1" (25.4mm) 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 A' Layer
Artwork placed on this layer will form the 'front' or 'side A' of your finished charm design.

Side A will contain your chosen holographic effect.

PLEASE DO NOT FLIP / MIRROR THE ARTWORK ON THIS LAYER.

'Artwork B' Layer
We print your designs in reverse onto the clear acrylic, before adding a layer of white ink and finally, your 'artwork A' artwork. When you turn your printed charm over and view it through the 'back' or 'side B' of the acrylic, your design will appear the correct way around.

ALL ARTWORK ON THIS LAYER SHOULD BE FLIPPED SO THAT IT IS A MIRROR IMAGE OF ITSELF.

'White' Layer

Adding a base layer of white to your charms will make your colours crisper and more vivid. Any printed areas without a white base layer will appear transparent.

'‘Cut Area’ Layer
Use this layer to show us where you would like 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 2mm between your artwork and your cutline. 

Failure to leave a 2mm 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 A' or 'Artwork B' layer and draw your designs directly onto these layers or, copy (CTRL+C) and paste (CTRL+V) previously saved artwork. 

'Artwork A'
Create or paste the artwork that you would like to appear on the 'front' of your charm here. DO NOT FLIP THIS LAYER.

We will print this onto the 'back' of the clear acrylic before adding a layer of white.

Your design will then be visible, the correct way around, via the 'front' of the acrylic. 

 

'Artwork B'
This is where you will create or paste the artwork that you would like to appear on the 'back' or 'side B' of your charms. ALL ARTWORK ON THIS LAYER SHOULD BE FLIPPED SO THAT IT IS A MIRROR IMAGE OF ITSELF.

 

We will print this onto the 'back' of the clear acrylic before adding a layer of white.

Your design will then be visible, the correct way around, via the 'front' of the acrylic.

4. Check your Alignment

If you're producing double sided charms it's important that your A-Side and B-Side artwork lines up correctly.

A simple way of checking this is to select your 'Artwork B' layer and lower the opacity to 50%



Now view your artwork and check that both sides A & B are the same size and nicely aligned. Here's an example of how it should look...

5a. Adding a layer of white

To guarantee bright and crisp colours for your artwork you'll 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.

An additional benefit of creating your own white base layer is that you can let us know EXACTLY where you would like us to print your white areas. This allows customers to add additional features to their designs, such as transparencies on our clear acrylics, as well as reducing any areas of white creeping around the edges of your artwork.

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 to inset your selection before inverting 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.

5b. Transparencies

The 'White' layer can also be used to create areas where you don't want a white base. This effect works especially well on our clear acrylics to create transparencies (areas with coloured ink and no white ink or areas with no ink at all).



To create a transparent area, simply delete any unwanted areas on your white layer using the eraser or any of the other tools at your disposal in SAI to achieve your desired effect. You can see this effect on our clear acrylic charms above.

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 2mm wider than your artwork. 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 2mm 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 40 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 of your cut line silhouette 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. 

Multiple holes - If you would like more than 1 hole in your charm, simply copy (CTRL+C) and paste (CTRL+V) the hole template onto your design.

The copy and paste command will create a new layer containing a duplicate hole template. This new layer will probably be called something like 'Layer1'.

Position the duplicate hole template over the part of your design where you would like an additional hole and click on the 'Merge Down Layer' button in your layers palette to merge the duplicate 'Hole Template' layer with your original 'Hole Template' layer.

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.

Multiple loops - If you would like more than 1 loop in your charm, simply copy (CTRL+C) and paste (CTRL+V) the loop template onto your design.

The copy and paste command will create a new layer containing a duplicate loop template. This new layer will probably be called something like 'Layer1'.

Position the duplicate loop template over the part of your design where you would like an additional loop and click on the 'Merge Down Layer' button in your layers palette to merge the duplicate layer with your original 'Loop Template' layer.

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...

  • Artwork on your 'Artwork A' layer has NOT been flipped.
  • Artwork on your 'Artwork B' layer HAS been flipped.
  • Your white base layer is Cyan and located on the 'White' 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 2mm thick.
  • Your charm template contains 1 charm only. Additional charms will be sent separately.
