Turn Sketches to Images With AI: From Product Design to Fashion. Complete Guide

Imagine stepping into a world where the lines between imagination and reality blur, a world where your sketches leap off the page and come to life. With the rapid progression of the AI revolution, we aren’t too far from landing in this reality – and the design industry is already at the forefront of this change. More and more designers around the world discover the potential of AI in pushing the limits of their creative processes in every aspect, from ideation and visualisation to streamlining their workflow and pitching concepts to clients.

AI: the designer's new ally

Contrary to common misconceptions, AI isn’t here to replace the designers. In the hands of talented creative professionals, AI can be an invaluable tool that amplifies their capabilities. This way, we are likely to see designers transitioning into the role of art directors, where their deep understanding of design principles, education, and experience guide the AI's output. This collaboration ensures that AI is not a replacement but an extension of the designer's vision.

The power of AI in product design lies in its ability to foster creativity and accelerate the process. By undertaking its more tedious and technical aspects, it frees designers to focus more on ideation and concept development. Designers find themselves spending more time contemplating and refining their products, leading to outputs that are not only visually appealing but also conceptually deeper.

Combatting the randomness

With all the marvels around leveraging AI in creative industries, it’s worth noting that these technologies are still far from being perfect. Most of the AI tools, including the popular DALL-E and Midjourney, are adored and actively used by designers but are still far too random and often overly too creative to be a reliable work asset. They may work wonders when it comes to seeking inspiration for creativity. However, the exact composition and silhouette a designer envisions might take hours to achieve with AI, or may not be achieved at all.

That’s where the sketch-to-image AI tools come into play. Such tools allow designers to guide the AI, marrying their creative vision with the machine’s computational power, to produce results that are both innovative and aligned with the designer's intent.

This technology, a blend of art and algorithm, is transforming the way designers approach the visualisation of their ideas.

Defining Sketch-to-Image AI

At its core, generating images from sketches is a process where a designer's hand-drawn sketch or CAD flat drawing serves as a blueprint for AI-generated visuals. This technology allows designers to set the basic composition or silhouette of a product, guiding the AI in creating a detailed final image. The process begins with the designer providing a sketch, which acts as a skeleton for the AI to flesh out. Along with this, the designer includes a description of what the sketch represents and what they envision in the final image in terms of aesthetics, colours, and materials.

How AI sketch-to-image software works

Once the AI receives the sketch and description, it adheres to the lines of the sketch to generate a product that aligns with the specified aesthetics, colours, and materials. An interesting aspect of this technology is its ability to interpret not just sketches but also photographs or other images as 'sketches.' In such cases, the AI disregards the colour but follows the contours and edges of the image. This flexibility allows designers to experiment with existing products, envisioning them in different styles, shades, and materials, thereby expanding the scope of their creative exploration.

Two key technological components in sketch-to-image AI are Stable Diffusion and ControlNet. Stable Diffusion is responsible for generating the images, while ControlNet ensures that the AI adheres to the lines and structure of the provided sketch. This synergy between the two allows for the creation of images that are not only creative but also accurate to the designer's initial vision.

For those with more technical prowess, options like using Stable Diffusion with ControlNet on a personal computer are available, albeit requiring a powerful GPU and technical know-how. Alternatives like Google Colab or RunDiffusion offer paid services but come with a steep learning curve. Amidst all these instruments, NewArc.ai stands out by simplifying this process, enabling designers to generate images seamlessly without the need to delve into the technical complexities.

Getting started with sketch-to-image technology with NewArc.ai

Step 1: Set up your NewArc.ai account

Before diving into the creative process, set up your account on NewArc.ai. As a new user, you'll receive 10 free credits, allowing you to generate your first 10 AI images at no cost. Once you're ready to explore further, you can upgrade your account for additional access.

Step 2: Upload your initial image

Begin by uploading an input image to NewArc.ai. This can be anything from a hand-drawn sketch, a simple line drawing, or a photo of the product you’d like to redesign. 

For this manual, we will use a shirt sketch created by CAD for Fashion:

Step 3: Describe your image

Provide a clear description of the key elements and specifics in your input image: try experimenting with colours, materials, styles and patterns. This helps guide the AI in generating images that match your vision. The more precise the description, the more accurate the result is likely to match your initial concept. Alternatively, the more vague the description, the more creative the results may turn out.

Step 4: Adjust your settings

Ensure even more control over your output by tweaking:

  • The style of the visual. For a design project, it would typically be a photo or a 3D render, but you can also opt for more creative formats like line art or even custom style like we did – this is totally up to you and is defined solely by your project requirements.
  • How creative you’d like the output to be. This setting allows you to define to which extent AI will follow the lines from the input image while generating images. In the “Accurate” mode, it will follow each and every line and curve, while with “Creative” it might not match the reference so precisely. This can lead to more diverse results, which often works best for the ideation phase.

  • What you would rather exclude from the image. In the “Negative prompt” tab, you can list the things you wouldn’t want in your designs, especially if you notice this feature coming up over and over again.

Step 5: Let the AI do the job

In just a few seconds, the tool will generate a series of images based on your description. At this stage, you can save the concepts that you like, and continue experimenting with the prompts to get even more variations.

Step 6. Fine-tune your favourites

Pick the concepts that best match your vision and tweak as needed. Sometimes you may want to merge the elements of two or three different concepts together – for example, if you like the overall design of image No.3, but would rather have it with the pocket from image No.1. Sometimes you may want to work on fixing the colours or the textures just a little bit, without scraping the whole concept. In any case, these alterations can be done:
