Create a Customizable Product

In MockSpark, there are two ways to create customizable products:
  1. Import a Third-Party Fulfilled Product.
  2. Create a Seller-Fulfilled Product.
This Quickstart tutorial walks you through the first method: import a Third-Party Fulfilled Product. To explore more about customizable product, visit Products tutorial. Click the Import Product button.
  1. Choose a fulfillment platform you’d like to use, such as Printify.
  2. Choose a product you want to sell, such as T-shirt.
  1. Choose a provider for this product or simply go with the default option if you prefer.
  2. Click Import to add the product to your product library.

​
Step 1: Edit Basic Details

After the product is successfully imported, you’ll be automatically redirected to its edit page. Here, you can customize the basic product details such as the title, description, and variants. However, for the Quickstart tutorial, we recommend keeping the default information provided by the fulfillment platform for now. Click Next to proceed to the next step.

​
Step 2: Create Mockups

In Mockspark, the Mockup is a core concept at the heart of our customization features. Every design function for customizable products is built around mockups. A customizable product lets you group different variants into separate mockup groups. This is an advanced feature that’s especially helpful when you want to display each color or style with its own specific mockup. But to keep things simple in this quickstart guide, we’ll apply all variants to a single mockup group for now.
To explore more about mockups, visit Products tutorial.
In this guide, we’ll walk you through creating two mockups (one for the front and one for the back of your product) within the default mockup group. Click New Mockup to open the Mockup Creator and build a mockup for your product.
To create a mockup, begin by clicking the button shown in the image below to upload a product photo.
Select or upload a front-facing image of the product.
In addition to using product images provided by your fulfillment platform, you also have the option to upload your own product photos. However, for this Quickstart guide, we’ll begin by using the default images from the fulfillment platform.
Click the Using this image button.
Click on the Print Areas section in the right-hand panel.
Click the Add Print-Area.
  1. Select the appropriate front-facing Print Area based on its name, and make note of its aspect ratio.
  2. Click OK to add this Print Area to your mockup.
Drag each of the 4 corners of the Print Area to the appropriate position on the product image.
In the Print Areas section of the right-hand panel, change Mesh Warp from 2D to 3D.
In 3D Mesh Warp mode, the Print Area’s 4 corner points will be replaced with a 4x4 grid, giving you 16 adjustable control points.
Using the Print Area’s aspect ratio as a guide, adjust the control points to reshape the Print Area. This helps create a more realistic and natural-looking product mockup.
If your product is White, we recommend changing the Blending Mode from Normal to Multiply in the Print Areas section on the right-hand panel. This will help enhance the mockup’s visual appearance for a more realistic effect.
For the best results, we recommend setting the Print-Area’s Blending Mode to Multiply only on light-colored products.
The Multiply blend mode creates darker colors by multiplying the base color with the blend color. In this mode, white areas in the blend layer become completely transparent and don’t affect the layers beneath, while black areas remain fully visible. It always darkens the image and never makes it lighter.
Click the Preview button to open the Personalizer and preview the current mockup.
Test your product in the Personalizer:
  1. In the Print Areas panel on the right, select the print area labeled front_dtg to start designing.
  2. Use the Elements panel on the left to add a design element (such as an image or text) to the canvas.
  3. Adjust your design on the canvas and review the product preview in the bottom-left corner to see if it looks the way you want.
  4. Click Back to return to the Mockup Creator.
If you’re happy with how your mockup looks, click the Save button to save your mockup.
We’ve already created a Print Area for the front of the product, now let’s set one up for the back.
Select or upload a back-facing image of the product.
Click the Add Print-Area
  1. Select the appropriate back-facing Print Area based on its name, and take note of its aspect ratio.
  2. Click OK to add this Print Area to your mockup.
Using the same steps as before, create a mockup that showcases the back of the product.
Test your product in the Personalizer.
If you’re happy with how your mockup looks, click the Save button to save your mockup.
After creating mockups for your product, click the Next button to save your work and continue.

​
Step 3: Publish Your Product

You can edit settings such as the product URL handle, Store currency, and Weight unit:
  1. URL Handle: A unique, user-friendly text based on your product title. It’s used to create the product’s web address in your online store.
  2. Store currency: It’s pulled directly from your Shopify store settings. To change the currency, simply update it in your Shopify Admin panel. For more details, visit: Shopify Help Center | Changing your store currency
  3. Weight unit: The unit of weight used for this product.
Shopify automatically formats your URL handle into a clean, SEO-friendly string containing only letters, hyphens (-), and numbers, but no spaces or special characters.
  1. In the variants table, select all variants by checking the boxes.
  2. Hover over the Bulk edit button and select Bulk Edit Price for Variants from the dropdown menu.
Easily update prices for all variants in bulk.
Once you’ve set the prices for all variants, click Done & Publish to list the product on your Shopify store.
Click the Check on Shopify to view the published product in your Shopify store.

​
Preview Your Product in the Store

Click the Customize button on the product page of your Shopify store.
If a product is not a customizable item listed through MockSpark, the design button will not appear on its product detail page.
If everything is working properly, you should see the Product Personalizer interface as shown below.
You can rest assured that the Mockspark Product Personalizer will always appear under your store’s domain. Your customers will stay on your site and won’t be redirected to an external page.
