You have chosen a print for your first collection, and the swimsuit mockup looks right. Now your manufacturer needs the artwork—but what should you send beyond the image?
Custom swimwear print file requirements involve more than the file itself. Your manufacturer needs to understand how the design should look on each style and which instructions to follow before sample development begins.
You do not need to become a print technician. Your role is to communicate the intended result, provide the artwork you have, and work with the manufacturer to resolve missing information before it becomes a sampling misunderstanding.
Share the Print Idea, Not Just a Mockup
A mockup shows how you imagine the finished swimsuit. The original artwork provides the design that will be used to develop the print, while a reference image helps explain a particular look. These materials serve different purposes, so label them clearly when you send them.
For example, you might like the spacing in a reference photo but want to use your own flowers. Say that directly. Without the explanation, the manufacturer may not know whether the reference represents the exact artwork or simply the feeling you want.
Send the original artwork separately from the swimsuit mockup whenever you have it. If a designer created the print, ask them for the artwork files rather than forwarding only the presentation image.
If you only have a screenshot or inspiration photo, explain that at the start. Agree who will prepare the usable artwork and what support is included; you do not need to solve that alone before opening the conversation.
Make the Intended Print Scale Clear
The same floral design can feel delicate or bold depending on the size of its flowers. A screen preview does not reliably communicate that size because the image can be enlarged or reduced without an obvious reference.
Instead of asking for “small flowers,” identify one flower in the artwork and give its intended width. You might mark a flower as 3 cm wide, for example, alongside a visual showing the look you prefer. That measurement is a design choice, not a standard requirement.
Consider each style in the collection. A flower that looks balanced across a one-piece may occupy most of a small bikini cup, so confirm whether you want the same motif size across both products.
For a repeating print, show the spacing and overall appearance you expect as well. If you are unsure how to describe it, ask for a layout showing the print at the proposed size on your chosen style. Your designer or manufacturer can then confirm how the repeat should be prepared.
Show Where the Print Belongs on Each Piece
A front-view mockup can leave half the design open to interpretation. Your manufacturer also needs to know what happens on the back and on any separate pieces in the set.
Imagine sending a bikini-top mockup with diagonal stripes but no view of the bottom. Should those stripes continue in the same direction, meet at the center, or create a different arrangement? None of those decisions should depend on someone guessing your preference.
Provide front and back views, and identify relevant areas such as cups, side panels, straps, and the waistband. Mark where a particular motif should remain visible and whether any areas should stay plain.
If your design uses placement printing, explain which positions matter most. A note such as “keep the complete flower visible at center front” gives the manufacturer a priority to review against the actual garment shape.
For exact positioning, ask who will prepare the layout on the garment’s pattern pieces. You can explain the visual result without drawing technical patterns yourself. Also discuss whether the artwork should stay the same size, move, or change scale across the size range.
Ask Your Manufacturer to Review the Artwork
Once the visual direction is clear, ask whether the artwork you have supplied can be used for the proposed fabric, print size, and style. A file that opens successfully is not necessarily suitable for the result you want.
Your manufacturer may request a different file format or higher resolution at the intended print size. Ask them to specify what is needed, then pass that request to the person preparing your artwork. Avoid converting files or changing settings simply because another supplier’s website recommends them; confirm the requirements for your own project.
If something needs adjustment, establish who will handle it and whether it affects the design. Making a flower smaller, changing the spacing, or simplifying a detail can alter the look of your collection, even if the change is suggested for practical reasons.
Ask to see any proposed visual changes before they become the new working artwork. This keeps technical preparation connected to your design decisions without requiring you to manage the printing process yourself.
Keep Artwork Versions, Colorways, and Tech Pack Notes Together
An updated artwork file can still cause confusion if it arrives with an old mockup. The same problem occurs when the email says “Blue Floral” but the attached placement sheet refers to a different color combination.
Treat the artwork and its instructions as one connected package. The person opening it should be able to identify the style, colorway, and current version without searching through earlier messages.
Identify the Current Version
Give each colorway—a particular color combination—a consistent name, and use it across the artwork, preview, and swimwear tech pack. Include a revision number in the filename, such as JB101_Blue-Floral_Artwork_v03, instead of relying on “final” or “latest.”
Your tech pack should reference the artwork and placement notes being used for that style. A simple record might look like this:
| Item | Example reference |
|---|---|
| Style and colorway | JB101 — Blue Floral |
| Artwork | v03 |
| Placement notes | v02 |
| Tech pack | v05 |
The numbers do not have to match; each document may have changed at a different time. What matters is that the record identifies the combination everyone should use.
Keep previous versions in a separate archive marked as superseded. Do not include several alternatives in the current package unless you are explicitly asking the manufacturer to compare them.
Record What Changed
When sending a revision, explain the difference in plain language. For example: “Artwork v03 reduces the flower width from 4 cm to 3 cm; placement is unchanged.”
Record the date, who approved the change, and what that approval covers. Update any affected preview or tech-pack notes, then ask the manufacturer to acknowledge that the replacement version will be used.
Use a specific status such as “approved for sampling.” This identifies the agreed artwork direction without implying that the printed color or finished garment has already been approved.
Confirm the Artwork Package Before Sampling Begins
Before development starts, bring the agreed information together in one clearly identified folder or email. This gives your manufacturer a complete reference instead of separate decisions scattered across messages.
A concise handoff should contain:
- The current artwork and its corresponding visual preview.
- Clearly named styles and colorways.
- Print-scale and panel-placement instructions.
- The linked tech pack and revision record.
Ask your manufacturer to confirm which package they will use and identify anything still missing. A reply that acknowledges the attachments is useful, but you also need agreement on what will actually be developed.
Clarify what the digital preview represents. It can help communicate layout and the intended appearance, but it cannot establish exactly how the print will look on fabric. Ask what physical confirmation is planned, such as a small printed fabric test, often called a strike-off.
Detailed color approval for swimwear is a separate step. At this stage, the goal is to agree which decisions are settled and which still need a physical reference.
Some details may intentionally remain open for development. If you want to compare two print scales, state that clearly and agree how they will be presented. If the manufacturer still does not know which colorway you selected, resolve that before work starts; it is missing direction, not something the sample should decide for you.
Give Your Sample a Clear Starting Point
Preparing artwork is about making your idea understandable, not mastering print software. Clear instructions give the manufacturer a useful starting point and help you distinguish an intentional development question from an avoidable misunderstanding.
If you are preparing your first printed collection, share your artwork, style references, and available tech-pack notes with Joy Bikini to discuss what needs clarification before swimwear sample development.
