[LemonInk](https://www.lemonink.co/how-to-use/woocommerce) is a cloud service used to secure digital books from piracy. It applies a digital watermark to each purchased ebook making it unique and traceable. Using this plugin, you can easily integrate LemonInk into your WooCommerce store just by marking products as downloadable and assigning a master file (the original ebook) to them. After each purchase LemonInk will create watermarked versions of your ebooks and attach them to user’s order allowing them to easily download their individual copies. Note that you need to have an account at [LemonInk](https://www.lemonink.co), but you can easily set it up just by [registering](https://www.lemonink.co/register). In order to watermark files you’ll also need to purchase some credits, but if you just wish to give it a try, there’s a test mode available. For more information go to [LemonInk](https://www.lemonink.co) or drop us a line at [hello@lemonink.co](https://cn.wordpress.org/plugins/lemonink/hello@lemonink.co?output_format=md). ## 安装 1. Upload the plugin files to the `/wp-content/plugins/plugin-name` directory, or install the plugin through the WordPress plugins screen directly. 2. Activate the plugin through the ‘Plugins’ screen in WordPress 3. Go to [API keys section at lemonink.co](https://www.lemonink.co/settings/api-keys) and generate a new API key. Copy the token. 4. Go to WooCommerce->Settings->Integration->LemonInk screen, paste the copied token and save. 5. Add a master file at [lemonink.co](https://www.lemonink.co/masters) and copy it’s ID. 6. Edit the product you wish to watermark using LemonInk, mark it as Downloadable, make sure that “Watermark downloads using LemonInk” checkbox is checked and paste the ID into the “Master file ID field”. Save. Any subsequent purchases of this product will be served watermarked versions of your ebook. Enjoy!

I used a different plugin for securely selling ebooks and when it deteriorated I researched several others. Lemon Ink turned out to be the best choice for preventing piracy without inconveniencing purchasers. Note that unused credits expire one year after purchase, so a) don’t buy more than you expect to use up within one year, b) use Lemon Ink’s system for automatically purchasing any number of credits when you are about to run out of them. ![](https://secure.gravatar.com/avatar/1c29b040349ce2351857397fcde7e742e100a2d996adcc3d6da27ef80ea843ea? s=60&d=retro&r=g) ### 󠀁[Great plugin and excellent helpdesk](https://wordpress.org/support/topic/great-plugin-and-excellent-helpdesk/)󠁿 [anndelaetepo](https://profiles.wordpress.org/anndelaetepo/) 2025 年 5 月 22 日 Plugin works absolutely fine. We are very happy with it. And with the helpdesk. When we encountered a problem (it turned out we ourselves made a mistake), the helpdesk responded promptly and investigated the matter thoroughly. Problem solved in no time! ![](https://secure.gravatar.com/avatar/491746e12db5b974a8d6654a9560d3eff4efe375385c71640ec4b659b15332bc? s=60&d=retro&r=g) ### 󠀁[Absolutely wonderful plugin and support](https://wordpress.org/support/topic/absolutely-wonderful-plugin-and-support/)󠁿 [Magmadiver](https://profiles.wordpress.org/fylpa/) 2022 年 11 月 2 日 Lemonink made it so simple and elegant. We were really struggling with our older DRM system, with multiple complaints weekly and poor UX. Lemonink is super easy for the customer, super intuitive for publishers and comes with great support. The developers are active and listening to our comments and addressing them timely. ![](https://secure.gravatar.com/avatar/852bda8b39fd1f9fd8e05c3438a8062231f29f619011a1241b1363c93a23eba2? s=60&d=retro&r=g) ### 󠀁[Works perfectly](https://wordpress.org/support/topic/works-perfectly-2291/)󠁿 [Mordimer_PN](https://profiles.wordpress.org/mordimer_pn/) 2021 年 6 月 17 日 The plugin is super easy to configure on the WooCommerce backend. Whole process of watermarking works seamlessly. User Panel on the lemonink.co is clear and intuitive too. What’s more, the support team answers ultra fast and is very helpful 🙂 ![](https://secure.gravatar.com/avatar/784bc021bd6ae21a74ca36809df2c085af7b6b673f0124e3932ebcfd67786c85? s=60&d=retro&r=g) ### 󠀁[Best Support on WordPress](https://wordpress.org/support/topic/best-support-on-wordpress/)󠁿 [editorialteracora](https://profiles.wordpress.org/editorialteracora/) 2021 年 4 月 22 日 We have been using Lemonink to protect the books of our publishing house, and it works very well. Simple to integrate and best of all, whenever there is a problem, let’s say a document is too large, the support team answers very quickly. We are happy to work with a very responsive support team. Not easy to find on Wordpress. ![](https://secure.gravatar.com/avatar/c8a4ca606c736d8aa273ee88204a7b74b7ad13a8ef8355bfd8f541b34bcfc28b? s=60&d=retro&r=g) ### 󠀁[Very happy I found this plugin and service](https://wordpress.org/support/topic/very-happy-i-found-this-plugin-and-service/)󠁿 [munikho](https://profiles.wordpress.org/munikho/) 2021 年 4 月 9 日 I’ve just started using this plugin and service and I am super happy with it. The support and response time of Piotrek (one of the developers) was super fast and very helpful. This was also the exact kind of social DRM I was looking for: simple, subtle, affordable and easy to implement. Happy I found them… [ 阅读所有10条评价 ](https://wordpress.org/support/plugin/lemonink/reviews/) ## 贡献者及开发者 「LemonInk Ebook Watermarking for WooCommerce」是开源软件。 以下人员对此插件做出 了贡献。 贡献者 * [ Piotrek Bator ](https://profiles.wordpress.org/lemonink/) 「LemonInk Ebook Watermarking for WooCommerce」插件已被翻译至 1 种本地化语言。 感谢 [所有译者](https://translate.wordpress.org/projects/wp-plugins/lemonink/contributors) 为本插件所做的贡献。 [帮助将「LemonInk Ebook Watermarking for WooCommerce」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/lemonink) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/lemonink/)，查看[SVN仓库](https://plugins.svn.wordpress.org/lemonink/)， 或通过[RSS](https://plugins.trac.wordpress.org/log/lemonink/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/lemonink/)。 ## 额外信息 * 版本 **0.8.4** * 最后更新：**2 月前** * 活跃安装数量 **100+** * WordPress 版本 ** 4.4 或更高版本 ** * 已测试的最高版本为 **6.9.4** * 语言 * [English (US)](https://wordpress.org/plugins/lemonink/) 和 [Latvian](https://lv.wordpress.org/plugins/lemonink/). * [翻译成简体中文](https://translate.wordpress.org/projects/wp-plugins/lemonink) * 标签 * [downloadable](https://cn.wordpress.org/plugins/tags/downloadable/)[downloads](https://cn.wordpress.org/plugins/tags/downloads/) [e-commerce](https://cn.wordpress.org/plugins/tags/e-commerce/)[ecommerce](https://cn.wordpress.org/plugins/tags/ecommerce/) * [高级视图](https://cn.wordpress.org/plugins/lemonink/advanced/) ## 评级 5 星（最高 5 星）。 * [ 10 条 5 星评价 ](https://wordpress.org/support/plugin/lemonink/reviews/?filter=5) * [ 0 条 4 星评价 ](https://wordpress.org/support/plugin/lemonink/reviews/?filter=4) * [ 0 条 3 星评价 ](https://wordpress.org/support/plugin/lemonink/reviews/?filter=3) * [ 0 条 2 星评价 ](https://wordpress.org/support/plugin/lemonink/reviews/?filter=2) * [ 0 条 1 星评价 ](https://wordpress.org/support/plugin/lemonink/reviews/?filter=1) [Your review](https://wordpress.org/support/plugin/lemonink/reviews/#new-post) [查看全部评论](https://wordpress.org/support/plugin/lemonink/reviews/) ## 贡献者 * [ Piotrek Bator ](https://profiles.wordpress.org/lemonink/) ## 支持 有话要说吗？是否需要帮助？ [查看支持论坛](https://wordpress.org/support/plugin/lemonink/)
