Editorial Policy

Who is responsible

Everything here is decided by Prasad Bhosale, who runs the site. There is no volunteer pool, no contributor network and no syndicated content: every sheet on this site was made for this site.

If something on a page is wrong, one person is accountable for it, and the corrections section below is how to reach them.

Where AI is used

It matters which kind of sheet you are looking at, so this is stated plainly rather than blurred together.

Coloring pages are made with AI. Apart from three early pages drawn in code, each picture is drawn by an AI image model from a written brief. The text on the page — the title, the description, what the page practices, how to use it and the age range — is written by an AI language model that is shown the finished drawing, so that it describes the picture that is actually there rather than the one that was asked for. The introductions to the coloring themes are written the same way.

Worksheets are built in code. The tracing sheets, letter and number formation pages, counting grids and matching puzzles are drawn by programs kept in this site's source code. A letter-tracing sheet is not a picture of a letter — it is a stroke path, drawn with single-stroke engraving fonts so that a dotted guide has one dot per pen stroke rather than two rows of dots outlining the letter's shape. That distinction is invisible on screen and obvious to a four year old holding a pencil. Each sheet's text is written for that sheet in the same code, and every one of these sheets can be rebuilt from it. Most of that code, and the text in it, was written with AI coding assistants.

Most of the small pictures on worksheets — fruit to count, an animal to match — are AI-generated line drawings, made the same way as the coloring pages. The maze series was built outside this site's code, by programs written in an AI coding session, with AI-drawn start and finish pictures, and is imported as finished pages; a checking program solves each maze from its file and confirms that every number its description quotes, from the length of the route to the number of dead ends, matches the maze.

What a coloring page has to pass

Before a drawing becomes a printable page, automated checks measure it. It has to be large enough to print sharply, mostly white paper, inked enough to be worth coloring but not so heavily that nothing is left to fill, drawn in outline rather than shaded, and black and white rather than tinted. A drawing that fails is redrawn with a stricter brief, and one that still fails is not published.

The drawings that pass are flattened to solid black lines on white, cropped to the drawing and given a consistent margin, so that they print cleanly at full size.

How the coloring pages are reviewed

The checks make a drawing printable. They cannot tell whether it is good, whether its title reads well, or whether it is filed under the right theme. Those problems are found after publishing, by crawling the live pages with automated checks and AI-assisted review, and they are fixed in batches that are read and approved before they are applied. Corrections to a page's text are drafted with AI help, working from what the page already says. In September and October 2026 these batches rewrote titles, search descriptions and theme filing, cut sentences that repeated from page to page, and withdrew pictures that were near-copies of another drawing on the site.

An automated audit also reads the text of every live page for problems a reader would notice: claims that do not match the catalogue, formatting that did not render, spelling that does not match the rest of the site, and sheets rated outside the ages this site is for.

Characters we will not draw

Many popular coloring subjects are trademarked characters, often described without being named — a cheerful mouse with big round ears, a yellow square sponge, an ice princess with a braid, a mustached plumber. None of them is drawn here.

They are excluded by an explicit, reviewed list of specific entries rather than by matching words, so each decision can be checked in both directions. The list also records what is deliberately not excluded and why: two generic robots, a carrot-nosed snowman, a dalmatian (a dog breed, not a film), and the public-domain fairy tales, Red Riding Hood and the three pigs among them.

If a restricted subject is ever drawn, it is filed as a draft and never reaches the public site without a deliberate decision.

That list covers the coloring pages. The pictures drawn for worksheets and mazes are not run through it, and in October 2026 two maze pages were withdrawn because their start pictures, a train and a race car with faces, came too close to well-known characters.

We would rather have a smaller catalogue than an infringing one. This is also why the site carries a copyright and DMCA page: if you believe something here copies your work, that is the fastest way to reach us, and it will be taken down while it is looked at.

How ages are decided

Every sheet carries an age range. On the worksheets it is set for each sheet in the code that builds it. On the coloring pages it is proposed by the AI model that writes the page, from the finished drawing, so a picture that came out more detailed than planned is rated on what it turned out to be: fine internal detail, like a rangoli pattern or a peacock's tail, raises the lower bound.

No range goes past five, the oldest age this site is for. In October 2026 the pictures that had also been rated for older children were capped at five, and their descriptions no longer recommend them to older children.

Ages are still a judgment, and they are the thing most worth telling us about if you disagree. A sheet that frustrates your child is more likely to be rated wrong than your child is to be behind.

Corrections

If something here is wrong — a broken download, a sheet that does not print at the right size, a factual error in a guide, an age range that is plainly off, or artwork you believe copies your own — tell us at hello@printkoala.com or through the contact form.

What happens then:

• Anything unsafe or infringing comes down first and is discussed second. We do not leave a page up while we deliberate.
• Factual errors in guides are corrected in place, and where the correction changes the advice rather than fixing a typo, the article says what changed and when. Silently editing an article to make it look as though it never said the wrong thing is not a correction.
• Broken or mis-rated worksheets are fixed or withdrawn. A withdrawn sheet is archived rather than deleted, and its address either leads to the sheet that replaced it or says plainly that the page is gone.
• You get a reply, including when the answer is that we think the page is right.

Advertising does not buy coverage

Advertising is how the site is meant to pay for itself. Advertisers have no input into what gets made, no preview of it, and no way to have anything removed. Nothing here is sponsored, affiliate-linked or paid for, and if that ever changes it will be labeled on the page it affects rather than disclosed once in a policy nobody reads.

Ads are kept off pages that exist as steps in a flow rather than as content — download screens, search results and error pages carry none. The coloring pages and their online coloring screens carry no advertising either.
