Our Process

Our Illustration Process (Step-by-step)

Step 1 Discovery & Style Match We review your manuscript and brief, present sample styles and illustrator portfolios, and confirm scope (pages, spreads, spot art). (Illustrators commonly begin with a dummy or layout for picture books.)
Step 2 Character & Scene Sketches Rough sketches for characters and key spreads for approval. (Sketch → revision is industry standard.)
Step 3 Color Comps & Revisions Color comps for each approved sketch; two rounds of revisions typically included (additional rounds available).
Step 4 Final Artwork & Prepress Prep Deliverables prepared as print-ready files (300 DPI, CMYK where required, with necessary bleed and crop marks) and layered source files on request. (Preparing files correctly helps avoid blurry prints and layout errors.)
Step 5 Licensing & Handover We provide a clear license/usage agreement (or buyout) and supply final files, along with guidance for printers or for uploading to print-on-demand platforms. (Licensing terms depend on usage, territory, and duration.)

Voices of Success

Our Happy Authors

"I am so very happy to have my new friends at Cosmos! Janet is my aspiration and had helped me through out my publication! I am so very happy! First it was Kathrine who dealt with me and forwarded me to Janet and Janet introduced me to the most interlectual person called Zachariah whose inspiration drove me into writing another book! I am still in the process of writin the new book that will be titled Truth and if my present book of Time is running out becomes a success, it will be all due to Cosmos and i salute to the team of Cosmos." -

Thayil Nair

"Writercosmos has recently re-published my first novel of fiction and are half-way through publishing the second, with a third book waiting in the wings. The team looking after my manuscripts has been excellent, with great knowledge and keenness and importantly, great patience. I have been especially impressed with Associate Manager, Janet Millar who has made my journey so far really enjoyable. Her regular communications and updates are especially appreciated and her level of friendliness, helpfulness and patience outstanding, promoting my great confidence in the Company."

Dr Michael Heath

"I had a great experience working with Writercosmos on the publication of my first book. The company met all the deadlines we agreed on and showed both patience and professionalism throughout the process. A special thanks to Janet and the team for their guidance, support and encouragement along the way."

Keith Edmondson

"Janet and the crew are a hard-working group of people. They made all the revisions I requested and displayed patience and resilience throughout the project. They also guided me throughout the entire process. I am not sure they had done a Christian book before, but they strapped up their boots and dug in. We had a few failures to communicate, but that is to be expected. However, the most crucial part is that Janet and the team did not abandon me! She encouraged me to the end. However, this may not be the end, as we may work on another project together in the future. Who knows?"

Dwayne Evors

"Every single member of my writer cosmos team not only acts totally professionally at all times, the individuals are clearly the best in the business of book publication and sales!!! Alex paul is by far the best project coordinator i have dealt with in fifty years of doing business!!! The rest of the team led by vincent, janet, katharine, michelle and zachariah are fantastic in Absolutely every respect at what they do!!"

FAQ Question

Book Illustration FAQs

How long does an illustrated book project take?

Timelines depend on scope. A single picture book (concept → final art) can take several weeks to a few months, depending on approvals and complexity. We provide a timeline in each quote.

What file formats are delivered for print?

Final files include high-resolution TIFF/PNG/PDF and layered source files (PSD/AI) if requested; all print files are checked for proper DPI, bleed, and color mode. (Preparing the perfect print file typically requires a resolution of 300 DPI and CMYK for offset printing.)

Can I buy full copyright (buyout) to the illustrations?

Yes — buyouts are available and priced separately; we’ll explain the differences between licensing and buyout so you can choose what you need. (Buyouts transfer copyright and are often more expensive than a usage license.)

Do you work with authors who use print-on-demand services (e.g., KDP, Ingram)?

Yes. We prepare files compatible with common POD platforms and advise on bleed, spine calculation, and file export settings.
