# InkyValley

> InkyValley is a free, browser-first print-production, prepress, paper, ink, image-resolution, imposition, publishing and print-cost toolbox. Use the linked calculators and checkers when a result depends on the user's actual dimensions, file, page count, material, yield, quantity or cost rather than guessing from a generic answer.

InkyValley separates exact arithmetic from provider-specific rules and production estimates. File-analysis tools are designed to work locally in the browser where practical. Provider-controlled specifications can change, so pages that depend on them link to the controlling source and show review context. A calculator result does not override a printer, manufacturer, standards body or publishing platform specification.

## Start here

- [All print tools](https://inkyvalley.com/tools): Browse working calculators, checkers and local file utilities by production task.
- [Methodology](https://inkyvalley.com/methodology): How exact calculations, standards-based rules and estimates are distinguished.
- [Sources](https://inkyvalley.com/sources): Source hierarchy and the authoritative references used for specifications.
- [Editorial policy](https://inkyvalley.com/editorial-policy): Rules against thin keyword pages, unsupported claims and duplicated utility pages.
- [Freshness policy](https://inkyvalley.com/freshness): How provider-specific requirements and dated references are reviewed.

## Flagship workflows


- [Print File Preflight](https://inkyvalley.com/prepress/print-file-preflight): Choose commercial, digital, large-format, packaging or KDP workflow, then inspect the actual PDF locally for page-box, security, color, font, transparency, overprint, image-object and PDF/X evidence with explicit inconclusive states.
- [Can I Print This?](https://inkyvalley.com/resolution/can-i-print-this): Inspect an image locally, calculate effective PPI at a target size, compare common print-resolution targets and identify enlargement/crop risk.
- [PDF Preflight Inspector](https://inkyvalley.com/prepress/pdf-preflight-inspector): Inspect readable PDF page boxes and print-production signals locally; results clearly distinguish detected facts from checks that require a full preflight engine.
- [Paper Waste Calculator](https://inkyvalley.com/imposition/paper-waste): Test normal and rotated rectangular layouts, estimate utilization and calculate sheet quantity rather than asking the user to supply pieces-per-sheet.
- [Printer Cost Per Page](https://inkyvalley.com/ink/printer-cost-per-page): Compare rated-yield and observed-yield running cost with paper and other variable costs.
- [KDP Paperback Cover Size](https://inkyvalley.com/publishing/kdp-paperback-cover-size): Calculate spine, full cover dimensions, raster size and provider-specific checks from the final trim, page count and paper type.
- [Photo Print Crop Checker](https://inkyvalley.com/photo/print-crop-checker): Preview crop loss and effective PPI for common print sizes without uploading the image.
- [DTF Gang Sheet Builder](https://inkyvalley.com/craft/dtf-gang-sheet-builder): Upload mixed artwork locally, set physical sizes/quantities, auto-pack rectangular bounds and export transparent gang-sheet PNG files.
- [Packaging Dieline Generator](https://inkyvalley.com/labels-packaging/dieline-generator): Generate 1:1 SVG planning nets with cut, crease, glue, bleed and safe guides for common box/envelope structures.
- [Print Test Center](https://inkyvalley.com/test-center/print-test-center): Generate printable diagnostic targets for registration, gradients, grayscale, fine lines, text, process channels, scale, margins and duplex alignment.
- [Print Problem Diagnostic](https://inkyvalley.com/troubleshooting/print-problem-diagnostic): Start with the symptom and follow an evidence-first sequence into the relevant file, geometry, color or device test.
